ok this is what I had 6 guys saying simple no problems even the engine seller ,then had 6 guys saying you will change everything ,an its a B,we we know who was right the 6 guys that said it would a B ,now it is what is is an will be a work in progress for awhile but its running I am driving it ,an yes there are some ****** to work out ,you all have nice cars I was just saying some would put a used part wear it makes no sence to me ,yes there is few jerry rigs will work out soon enough I got the drop down base plate offset forward 14x3 waiting fro the rest ,I got small fire exst just in case most guys buy them for looks an or emergencies ,I agree there is a lot more air flow with headers ,each cyclender breaths right on its own ,,work in progress value is a matter of opion yes if I don't keep the lt1 in it ,an I did not say it was rare In value. rare in being done ,I will still have 12 to $14,000 apraisel insurance on it next year ,wich would surely get me a desent replacement car .like said I stoped paying for it 2 years ago ,if paying on ,I don't spend money I don't have in my pocket ,so 3 years or less this part is paid for ,I got it for $4600.00 in 2008 with 69000 miles was worth it to me the red t handles for looks an I like them they were $30.00 ,there staying see guys its what one pseron likes another does not so its different strokers for diffrent folkers ,though in 5 years mabey it will be stroker I like adventure ,this one know ,but next time will find a 76 with no engine or tranny I had seem 1976 was fresh paint trim ,needed the inside redone but was solid 3400.00,a shock tower brace like crabys I am getting just for looks I don't exspect a $90.00 brace to do much other then look good .now a good one it 300.00 to 700.00 lets see if I won the lottery last night ,its all good thanks guys .so the reason no headers is much labor that was not expected ,otherwise iwas going to get them for an lt1 ,now I will just get some sbc shorty headers an modify them to straight pipes like said ,no more y pipe no more cat ,yes 30 more Hp,iwas told buy a Gm mech people reuse worse then the lt1 manifolds an there actually not that bad ,the the cat ,or combo,its still sounds a lot louder an powerful then the stock lt1,ina richer world ,I would have got an lt1 383 an all the nice thing that go with it ,I gm built 383 is like $9000.00 alone or more ,don't hold me to anything I say heehehehe

95 Camaro 406, I understand you are doing things in phases, and covering what fits into your budget at the time. So far, I'd have to say nice job, the engine swap looks great. I like the old school look, and there's something about having an engine in a compartment that doesn't require the use of a shoe horn to get in there to work on it.
that's cool what you said ,don't know why I like them ,but they can come off pretty fast ,they has the open hole was my thought an they were cheap ,is it the color they have chome ones ,to me it gives it the olod school look ,yes you can fill up 55 gallon drum with the parts that are gone now ,don't hold me to that ,but I do think my calculatation is its about 150lbs to 200lbs lighter to ,about 40 on the tranny an 150 on the engine ,thoug I am pretty sure someone may straight me of that to ,thanks you got the nicest car of us all .beauty is in the eye of the beholder I know some guys don't like stickers I think the few add to the look though going to cover them with the chrome radiator cover ,an all the other chome componants ,will buy in winter ,an the parts for the rear in crabys link he posted an be already for spring next year ,I learned a lot with all you guys help thanks again ,mabey I can be some help now too,i do like to help an not just take

If the"crate" motor is from anyone but GM it is just a rebuilt motor. GM crate motors are new. You can buy rebuilt LT1's for the same price as Gen 1 small blocks. I have never seen much difference in cost between LT1 parts and SBC parts. You can hit 400HP pretty reasonably in a LT1. 425-450 can be done on stock parts in good condition.

This is from a respected race engine builder. They can be found cheaper from less known builders.
https://www.golenengineservice.com/e...on-short-block

Send your heads/intake to get the LE2 mods and the buy the right CAM for you, send your PCM out get it tuned for what you bought. One guy working about 20 hours later your done. Yes you will still have things that will need to be upgraded but if you plan it right and have a friend you could be done is a weekend 6K later.

I am not posting this to beat you up about the build but the only person that would recommend getting rid of fuel injection would be someone that does not understand it and is afraid of it. In a race car carb is fine but on the street fuel injection handle the changes much better then carbs. In fact you can find a lot of gen 1 small blocks these days used in perfect condition because their owners are pulling them to put in fuel injection engines. I have seen guys spend a lot of money converting their hot rods from the good small block to a LT1 system. Many of them paid more money to get rid of what you just installed then you paid to have it.

FYI you old stock intake and/throttle body and injectors are worth about $300. They can be used to convert a small block over to fuel injection. You could keep them and maybe convert to fuel injection and add MSD's Pro-Billet Front Drive distributors

I guess I don't remember this being a thread about fuel injection an carbs being better I agree,but I also know that a carb can be tuned to run just as well .opinions vary!,don't worry your not beating me up ,an its new to me ,an that's all that matters.lets move on to ,the best way to get proper power from the one wire 70amp alternator ,someone said you can reverce the power to make it work right again don't hold me to it,or hook the power to the 2 porongs on the back ,other choise is to get a more powerful one ,then move on to gauges I want to get a set up that has oil temp an volts in one ,then there is the speedo cable I can convert ,I think doing that an getting the gauges that are small enough to put near anywhear without tearing up the dash ,then there is getting a different cluster altogether ,you had gorn a pic of one in another post ,it to weigh the pros an cons ,my fuel guage still works ,ai allways wanted an oldschool rod ,I had 77 Eldorado with 425 ,that about as close as I came ,was pretty fast for such big car ,At 47 I think theres enough life to ,go back to FI one day ,not with this car but perhaps another one ,then again one day could make this one to handle 600hp ,who needs that for the street ,anyone price a new z28,if I won the lottery I would not buy one ,now a real 500 gt yes ls7 is it yes I was a ford guy all my life mosty ,actually I like them all ,now that I think when I am thinking like a man an not a kid ,anything with a motor is cool ,like a supped up lawn mower ,life is to short to have plans to far out ,an too short to not have some plans for next year as well,like headers I carb cost #250.00 average an changes much quicker ,an i can do it myself probley ,though I am just want to be ,not certed mech ,just like I sell jewelry on ebay but I am not a gem expert ,but just may know a few more things then the average person .like my mech went on a trip to brazil they handed him sapphire said go in there an have it set in silver or gold ,I told him it was to suck him in ,that the sapphire is nice ,but man made ,good sapphire is so rare ,say blue ,it can cost 10.000 per carat 3 carats or more ,tanzanite I can get for 1% of that .if I shop for it ,point being he just did not know couse unless its tested it looks exactly the same ,so the real point is his wife has been wearing a man made sapphire on her finger for years as well as many others ,couse they just don't know ,live an learn,an who know mabey while increasing the hp will change the manifold to fit a throttle body injection on it ,now again that may be possible it may not be,i am guessing there ,with the gems I don't guess I test them an when In doubt ,if its to good to be true it probley is,will give it a determined an persistent trial an see what happens I think the next year will tell ,for now I cant afford to many regrets,thanks for that info I have seen whole lt1 engines selling for 200.00 on ebay though ,an probley can part it out for more over time ,I would keep it just don't have the room I don't want to be pack rat ,I hear its the heads that are worth the most was that a few years ago, i will now think about keeping what you mentioned though,

Based on your description I am not sure what you are trying with switching wires on the alternator. The only reason an old school alternator needs two wires is so the regulator could see voltage that was not directly from the alternator itself. Single wire system do not control voltage as well because there is no compensation for voltage drop. The third wire on a old school alternator is just for the dummy light.

(voltage drop would indicate how much power is lost in the system due to resistance in wires and grounds.)

As a general rule the only way to increase the out put of an alternator is to increase how fast it spins. If you search "full fielding a GM alternator" You should be able to find how to check you alternators max output at a given RPM.

Fans and fuel pump alone should not be a problem for a 70 AMP alt, A 1989 Z28 would comes with a 70 amp alt and with two fans, AC , fuel pump, radio, head light, wiper would be fine sitting in traffic for hours with a battery that was so bad it could only store 200 amps. (In 89 the factory battery would have been 400 CCA)

FYI the argument Carb vs EFI was huge in the 80's but by the mid 90's it was pretty much done. No one, I mean no one that has dyno tuned both EFI and Carb is going to claim the carb is better.(Not even the aftermarket carb manufacture claim they are better) If you have a race car that only needs to run well between 5700 and 6700 RPM you have a chance the carb can do as well as EFI. With carb tuning it is all about give and take. The carb might run lean at 2600 RPM and rich at 4200 RPM. You only get one jet size so you balance it.

EFI you have unlimited adjustments. How it is tuned for 4200 RPMs has NOTHING to do with how it is tuned at 2600 RPM. You can also program in logic like: if the throttle is less then 50% depressed run a tune designed to get the best fuel mileage. Over 50% its ***** out running. The EFI will monitor temps and even barometric pressure and adjust your fuel and timing to compensate. If you decide to crank you timing for max power the EFI has a knock sensor that would protect your motor from cheap or bad gas. The only good thing about carbs is they are cheap and easy for someone that does not know EFI. That is why in my book the swap makes no sense, swapping to a carb on these 4th gens is neither cheap or easy. You are paying money to give up the chance to have the same precision fuel system hot-rodders are paying 10k to have.

so mabey the bigger left over pulley I have may work ,ok with the other thing ,yes anyone with commen sence knows Fi is better ,but still there are some who will argue it ,I know fi is better ,I am not planning on driveing my car 40,000 miles per year anymore ,i had a friend that would not own Fi couse he had a few vans in the 80s the the injectors went on ,we now know that's very rare,so there are some still that wont own FI its getting much more rare ,couse there are not many cars left with carbs Fi is cleaner yes an better yes ,every now an then someones injection system goes they pay dearly in a newer car,yes I have 600cca battery from walmart yes I had one last 7 years +,i know some say they stink, I don't think I need an 850cca intersate right away ,like i said we know its charging at the higher rpms,he did say the other day we may have to get away from the one wire ,makes sence so it would take a bit of city driving to make it not want to start hear a few days about 3 days bye the 4th it would need a charge I just been putting it on trickle for a few hours before each drive,avarage is 2 hours on 2amp .yes I know trickle is less at about 1 to 0.5 amps,well this week got cover the hole on the fuel tank did not stink any worse then the old lt1 did ,they made my cap breathable ,couse finding one for that car,air cleaner I already know the base fits I fitted it ,hope i will have that one inch its important ,that other guys car that was poor design .though like I said his carb set further back looks as though unless he was using the offset stud an not thinking about the vibration,as far as pics I don't see any others just the one ,besides mine now,the other forum told me we could not do it ,I told them that's unacepable ,z28, something,not to mention they change peoples posts an threads ,I wrote them an told them they should take the thread down couse we did succeed an they were wrong,thats why when I got hear I was a bit discouraged ,but we did it ,not me we thanks gorn ,going for ride into town today,yes though oh well its done now ,I guess the 6 guys I listened to should be shot in the *** includeing me ,an the other are holding the whip,i got to say most people I talk to thinking its cool ,but there knowledge is limited ,don't hold me to but atleast one of the guy from street outlaws has a carbed engine ,mabey I should have done a bit more shopping around ,but its done ,an if I get another 5 years out of it great I got to say with the t tops I don't think I would want to go anymore hp ,so who knows next time I may look for the older one camaro that is to put a carbed engine hard top,like I often say I am not going to be raceing it ,though when we get the ****** out an the rearend beefed up I may go run 1/4th mile once ,I prefure the highway 65mph at 75 to 80 that everyone goes ,an no one in front of you.i looked at that site an 383 with 400hp was $5600.00 without the efi or alot of things like $7500.00 then a desent tranny an labor would have still been about 11.000 not to include headers or rearend build or ;labor ,mine can be done for $6000.00 without the labor,so it was not going to equal ,there was one engine on sale on ebay ,that someone did not pay for ,but is was an still need the upgrade to efi ,like I say I would have liked to go with something like that but it was about $3000.00 grand out of my range for the engine alone ,you know the cost of mine was 3600.00 ,but lets not debate it couse its done for now ,your right about my set up being worth $300.00 they go for like 3000.00 on up new I seen one for 2700.00 efi throttle body an manifold,trying to upload video of it running ,it wont upload gorn well I guess what makes sence to one person make none to another ,live an learn ,but I cant kick my own assis over this ,all we can do is get running great an finish the job one day at a time ,I love the sound an the 350 turbo no overdrive people hear you at 55mph ,I guess that what guys like about th350s ,an what makes the world go around is like the valve cover red hold downs ,to me right after I put them I on I saw improvement ,I sell gems on ebay I mentioned ,some want a tanzanite that is dark blue like sapphire ,an other will settle for size in the bi color I deal with ,couse it cost so much less too then darker blue ,as long as I am happy that's all that matters ,an you got a thread that seem to be more in depth then any other ,I am sure there arte guy who have done it that never posted any info,for me the look is much better then what I had ,like I said take away the labor ,a guy can do it for less ,yes mabey can do stock lt1 ,but they are not going to get 458tlbs ,I wanted bang for my buck ,live an learn with the labor,but now someone elce should be able to cut the time in half ,also think about how many guys got the engine sitting next to the car ,saying I wish only if ,they di not get there ,yes gorn your a gm mech right ,so you see it your way ,an I unserstand a lot of it,some not at all,if I went on about gems unless you know you may not know what I am takeing about ,but you may try it anyhow ,like the guy who buys the man made sapphire ,you think after say 10 years he will tell his wife an its fake an worth $5.00 ,my point again being it got done wear so many failed ,ir dids not go on ,it seems we had some success ,an it is what it is ,a 95 Camaro 406 carbed ,an so far driving it has been fun ,I can feel the power difference the moment I start it ,that what matters its looks desent ,an next year will look even better with more chrome,some guys don't care what its looks like only how it runs ,I like both ,take the guy that does not mind takeing 2 years building his car ,nothing wrong with that to him ,saveing alot in labor,for me i would shoot myself before takeing that long to build anything hehehee ,that's what makes us all different,diferent strokes for different folkes ,we cant impose our will on anyone ,but we can be helpful to there ideas an you all got some good ones an some well,we cant allways be right ,like one guy thought we would not be able to shut the hood ,like the person who talks about something you don't like ,but you listen couse you just do,see also I don't feel I am giving up anything ,somethings temporary yes ,but I got eh more hp I wanted,an got many years ahead to do something else wild an crazy one day like put efi 406 in the 1976 gen 2 ,probley not though I think it would still be carbed engine ,they drove them for 60+ years ,efi was what 1955 lincon had them ,an they were working on them earlier ,an is what 1984 hear everything was going efi.,like isay I would love to have the new camaro not the z28 ,but the other one with v8 ,who knows mabey in 10 15 years will try putting a 406 carbed in a 2013 camaro ahahaahha just kidding i think ,I had to chill out with this couse it was a ball breaking swap with blood sweat an tears an the mech was ready to drop the engine on his head ,one thing is atleast there is a bit more to talk about then the stock one

I still think a 600 carb is going to be too small for that many cubes. My 302 has a 780 on it (granted I pull to 7400) but still. The pictures in this thread were cool to look at but nobody wants to read a novel of a post with no punctuation or grammar/spelling usage whatsoever. Ain't nobody got time fo' dat.

well the engine builder put them together if anything its the cat an pipes that starve only a little thottle reponce has been good but I have been takeing it easy during breakin when I nailed it during the first 20miles it was great,I hear some cars are over carbed ,I asked many people that they said no you don't need a 750 or 650 or a 700,the engine builder I guess there opion matters most,beisdes I hear if I go up then I got hole in the hood as you have the rasie the carb ,dont hold me to that ,but its running fine I can feel the cat a bit ,heack just changing out the breakin oil is going to make a difference few more weeks about 400, miles I only been putting about 20 to 30 miles a day a few days per week,the carb needs good tuneing again but its not stalling,an that 14x3 the air filter should make a difference to ,I know aguys has a 750 on his 1979 350 an it did not come with he only added it ,an it sounds like it sucks even more gas ,asked about the whole getting more hp ,we got the reg at 4psi right now seems ok ,the 20.00 in gas I used to put in it is 30.00 that should even out a bit after breakin if I am getting 12miles per gallon a guess ,I don't want to move to 9 per gallon buy changing carbs the engine was built more for tlbs then hp about 300rwhp an about 330tlbs to the wheels so more bottom end then top end .but what do I know

well the 14x3 wont work but 14x2 will give me the clearance about an inch clearance an they sell the reuseable ones,had to order one though no locals had one ,the drop base is good don't think I need the offset forward ,the 3 was to tight ,cut it down an to 2 inches an taped it with gorilla tape for now,so guess when all is done atleast I don't need to mod the aircleaner looks pretty good other then the bit of tape showing a little for few days ,an I know the 2 will work too yes I know the tape catches fire to but its not right over the the top of the carb like the foam was ,it was to small too,an this one will look better an breath better moderators ATTETION I been sendin you all messages about loading profile picture ,an videos not response
