I dont want to sound like a dumbass whos asking poeple hwat they think his horsepower and torque is, but im a little frustrated. i mean i was talkin to my old man about my motor, and asked what he thought it was pushing for horsepower. he predicted about 275-300. those are decent numbers, but i looked at the stock 350's that came out in 1976, and they were all around 260 horsepower. ide figure i jsut list engine parts now and see what your predictions are. as for how the car runs, it has no problem spinning tire. it will wind all the way to 6000 rpm spinning tire, which having 11.6 inch wide back tires, i dont see a 265 horsepower v8 doing that. the cars bottom end torque is a little soggy, but when it hits 3000 rpm it really takes off. heres a list of parts installed so far.

-bored .030 over/rebuilt
-iron heads 2.02 intake 1.60 exhaust
-70cc combustion chambers, 8.5-9.0 compression
-comp cams hi-tech mechanicle 250/260 .532/.555 lift
-magnum pushrods and 1.52 roller tip rockers
-weiand x-celerator high rise single plane.
-650cfm barry grant coming soon.
-1 5/8" long tube headers
-true dual 2.5inch exhaust w/moroso spiral flows and x-pipe

any predictions on horsepower and torque would be appreciated. i jsut find it hard to believe that 260-300 horsepower is all it could have. 300 isnt a bad number at all, but i would hate to see it below 300 after all this money spent. it certainly feels like more then 260 when being driven.

How Long Is The Duration Of Your Cam @.050? I Know Lots Of People Think That High Lift Is What Produes Horsepower. It Has More To Do With The Duration Of The Lift. The Longer The Duration The More Fuel And Air It Inhales. Sick

250 degree intake duration, 260 degree exhaust duration.

This Is Just My Opinon Timmy But, Your Probably Producing More Torque Than You Are Horsepower. I Had Some Drag Racers Tell Me That Horsepower Isn't What Wins Races It's Torque. But Ya know Every Racer Will Tell Ya Something Different. Sick

i would say somewhere between 350-400 hp,just a guess

SSS, thats good news to me. i matched the cam with the intake manifold as best i could, and overall they both make more nuts onn hte lower end of the rpm's. i know hwat you mean though a lot say torque wins races and a lot say horsepower, but its actually hte combination of the two. you cant win a lot of races if you have 190 horsepower and 400 ft lbs of torque, and oyu cant win a lot of you have 400 horsepower and 190 ft lbs of torque. thanks though thats good news to me i would like torque ot be slightly higher.

Mine Is A Torque Hound As Well. If I Can Ever Get It To Hook Up I Believe I Can Turn Some Decent Times. Sick

If You Have A Degree In Math LOL This Site Tells You How To Figure Horsepower Good Luck. Sick http://g-speed.com/pbh/torque-and-hp.html

well i can give it a try, but not doing to good in math. thanks.

oh yea and my back tires are 295 50r15's, jsut goes to show what you can fit back there. about 11.6 inches wide. my tires were cheap but do give some grip, but im sure you would drop your et's right down if you threw on any pair of tires with a similar size. cant fit much bigger then that when it comes to width.

What is your duration @ .50? I am sure you listed the advertised duration. I hate to be the downer here but you really probably only making the area of 275 or so HP. Your heads and compression are really kepping you down. However your torque is well over 300 I am sure. Judging how much power you have by it being a burn out monster is not going to tell you much. If you ever get to a 1/4 mile track I can figure your HP off of your mph as long as you know the weight of your car, it's not dead on but usually is close enough for a good idea.

whats it really matter if it hauls ass and beats all the 500 HP drive in racers with only 300 horse sounds like a great time to me you know it all matters where you measure from (lol)

JD, the 250/260 is the duration at .050. i am actually looking into new heads right now. i wanted either the sportsman II's or edelbrocks performer rpm aluminum heads. i dont know whether i have flat top or dished pistons, is there an easy wawy to tell without taking the head off? anywyas edelbrock has 70cc heads and 64cc heads. would my compression be too high if put the 64cc heads on? thats jsut guessing that they are flat tops. but if i find out they are dished i will probably get the 64cc heads rather then the 70cc. i like the edelbrocks because they are aluminum one, but they are 960 dolalrs for both of them assembled, for aluminums thats not horrible. also when buying new heads, do i jsut need head gaskets? i do know of the bolt torque specs of my motor and stuff like that, but is there anything i need to buy besides head gaskets? i would be re using my rockers and pushrods.

For anybody that cares this how Hp and Torque relate to each other.

"Theoretical" best ET and trap speed are acheived by keeping the RPM between the torque and HP peak, and be revving at the power peak on top gear just before crossing the finish line.
When on top gear the car will accelerate the fastest when the engine revs at the HP peak
When in lower gears the car will accelerate the fastest when the engine is revving at the torque peak.

A dyno does not measure HP but calculates it by measuring the torque

These formulas only work if the torque is measured in ft-lb:

HP = (torque X RPM) / 5252
torque = (HP X 5252) / RPM

Magic number -- torque = HP at 5252 RPM (use this to impress or confuse your friends, or to start an argument.)

an update, i am now looking for aluminum heads, with 64cc chambers, 2.02/1.6 valves, and intake runners smaller then 200cc, preferably 180cc's. and a big one is they have to cost less then a grand. i know which head gaskets to get, going with the felpro #1010's. if anyone has a link to any website that carries what im looking for. the edelbrock performer rpm's are a ncie head and all, but i have heard not the BEST things about them, basically i hear there is better for less then a grand. any help is appreciated.

IF those are your numbers at .50 your cam is too big for a 350, it might be a good cam for a big inch small block or a car set up for very high rpm.s. Thats really is a ton of duration for such little lift.

JD all i know is it is a solid lift cam from comp cams. i searched their solid lift cams and jsut picked the one with the lowest duration, because the car doesnt behave like a top rpm car. certainly getting this motor blueprinted soon because im tired of not being 100 percent sure of whats in it. when it comes to the cam i am going by what i was told, but i know its a solid lift cam from not only being told, but the noise and how i have adjust the valves from time to time. i was not told its specs such as lift and duration, but the car has a decently smooth idle so i jsut picked the lowest duration one form comp cams.

Ok well i have one final question here. im looking at these aluminum heads with 160cc intake runners, 64cc chambers, 2.02/1.6 valves, with the kidney bean shaped combustion chambers. they are the ones i am getting. as for my motor, to finish it off, i am getting these heads, #1010 felpro head gaskets, comp cams 1.52 ratio steel roller rockers, not roller tips, a cog belt drive system with smaller crank pulley, and a barry grant 650cfm. shouldnt i be pushing close to or at 400 horsepower after these upgrades? i would certainly think so, but by the way none of these mods will be done until i get an 8 point rollcage put in which is coming up soon. as for the drivetrain its getting a 3.90 rear end, and having my tranny rebuilt into a th-400 with ratchet shift, along with an aluminum driveshaft. that will finish off the drivetrain and motor and is what i am planning on keeping it at. after that interior and exterior is next. but anyways to get at the point, would i be in the upper 300 to lower 400 horsepower range? and what would you say torque would be? i would guess around 370-390.
