I am currently building a 350 for my 1980 camaro. This will be a street/strip car. I am thinking about using:
Lunati voodoo cam
-268 duration -489 lift
world heads
-2.02/1.60 -64cc

edelbrock victor jr intake
1" taller version

holley 750 cfm carb

hedman hedders
-1 3/4 into 3in collectors

Is this a good setup? anyone with desktop dyno tell me how much horsepower i will be producing? Any different suggestions?

 

with heads like that and that intake,i would go with alittle more cam.now this is my opinion,if this car is going to be on the drag strip,i would be looking for more power on the top end.i think that intake is good to 7000rpm.the heads you are looking at are going to let it breathe real good.i would be looking at a cam that has alittle more lift(550+/-) and duration(280-292).

 

VOODO ARE GOOD COMP ETREME ENERGY PUT A DUALPLANE INTAKE ON THAT THING 2ND GENS ARE HEAVY YOU NEED AS MUCH TOURQE AS POSSIBLE AVIC JUNIER WOULD GIVE 5-8 MORE HORSE BUT YOU WILL LOSE 25 TO 30 POUNDS OF TOURQE MY 400SBC IS PUMPGAS DUELPLANE 2800STALL AND 323 GEARS HOCHKISS TVS SO IITS NOT SET UP FOR DRAG RACEING BUT NEVBER GETS TURNED PAST 6000RPMS 11.41 119.7 1.61 SIXTY FOOT .

 

Not enough info to determine the camshaft and build give a full rundown, compression, pistons, rods 2 bolt 4 bolt block.... gear ratio, trans, stall. The more info you can provide the better answer you will get.

 

The compression ratio is 9.5:1
A 4 bolt main block
stock bottom end
stock rods
hooked up to a 4 speed tranny
4.10 rear end

 

that combo you listed 360 horse would close to what yoU would get 1 34 hedders ar to big unless your turning past 7000 rpms a 1 58 is the way to go if your stuck with that victir intakre run a 4 hole spacer to give back some tourqe when i had a 350 in my chevelle it was a stock bo0ttem end 2 bolt main truck moter i ran the comp etreme energy 487/490 cam junk 3o5 heads performer rpm intake 750 double pump 1 58 headers in a heaVy 71chevelle i had less then $2000 IN THE CAR INCLUDE THE CAR IT SELF IT WENT 13.5 100MPH I DAILY DROVE IT .

 

The factory rods are the weak point right now I dont know how far you are into it you goals or your budget but we can start here. If the factory rods are to be reused they will need to be resized and new bolts and magnafluxing you can get scat rods for close to the same price and be much stronger. Did you already buy the heads(check out petes head flow chart sticky)The factory crank need to be magnafluxed but they will handle quite a bit of power(detonation kills a bottom end). A cam of a larger duration will negativly affect the dynamic compression ratio because the static compression is too low. I think you are in the ball park with the duration depending on the other cam specs. I too would suggest the dual plane manifold the 750 carb is to large for the single plane and could be a little big for the dual plane. My guess with the 9.5 to 1 compression is 450 hp. Give me a link to the cam card and I will run it on dd for you. We put together a junk engine last year, 350, factory crank, factory rods, hand honed and ringed unbalanced cast pistons, junk yard l31 vortec heads stock rockers, steel shim head gasket, dual plane 600 carb(too small) 79 camaro 4.56 gear automatic, 270 comp cam it ran a 8.23 in the 1/8th I think if we would havespent more time tuningit would have easily been in the 7s. We changed the cam to a smaller duration because of a bad lifter (24? duration and itended up running consistantmid 8s.

 

if you keep it under 6000 rpms your botem end will live if you went threw all that trouble to pull the motor, machine this machine that you can stroke it 2 383 for a liite more cubes rule.

that is the link to the cam i was thinking about
which dual plane manifold do you suggest?

I already have an edelbrok performer manifold. part #350-2102

I was also looking a sbc kit from jegs it includes
http://www.jegs.com/webapp/wcs/store...10002_50246_-1
2.02/1.60 heads
lunati cam dur 234/244 lift .488/.510
holley dual plane intake manifold.
is this a good kit and which carb would be a good choice?

 

That voodo will work the guy who invented that line for lunati name is harod brockhshire you can find him on the teamchevelle web site my dads ben useing him fot 30+years he will custem grind you a cam.he did a bigbblock cam for my dad for a 69 camaro it ran 9.9s 139mph this was on moter driven 2 the track on pumpgas also was a hydroller 3700 pond car. the cam is the brain of moter try geting a hold of him they call him ud harold. ultadyne camshafts was the name of his cam company but he sold the company to work for lunati i think he does nascar cams now he just did a cam for me for my bigblck its pretty trick with changed fireing order if you go to team chevell search for ud harold make sure you upgrade vavle springs to.use the duell plane 1-58 hedders 780 holley with vac secandarys will work good ihave to sets of vortec heads and a never taken out of the box airgap 4 vortecs with the poted set with a harold cam with yor stovk bottem end 430 horse no problem also have 2 udharod roller cams 530 lift 1.5 rocker igot a combo that wod give 460-490 horse easy also haVE A brand new moroso oil pan with windage try and crank scaper its worth 15 horse iran small bvlock for years but have moved on to big blocks thats why i have all these parts .
