ok i need a horsepower guesstimate i know it wont be accurate and im going to have a bunch of hate mail but people have been bugging me about this,
its a 350 standard bore and stroke
10.7:1 CR
ported 193 heads
.488/.488 292/292 cam
stock chevy 4 barrel intake manifold
holley 600-650 cfm (idk which one yet)
summit headers
if im missing some important part tell me please lol
thanks guys

step down one on that cam for more bottom end, and I'd guess HP to be around 335....but that's just a guess.

Do use a smaller cam. If you're going to use a small carb and a stock intake, I suggest nothing more than 262 degrees of duration at .005". You're motor will make the same horsepower as the engine with the larger cam, but will also make much more torque.

ok got it smaller cam. thanks guys
what do you think a 3500 pound camaro with a stock th350 and say 3.73 gears will run in the 1/4 mile?
and would 3.73 gears be good or should i go to a lower gear?

with the original combo, 353 HP @ 6,000, 368 Ft/lbs @ 4,000

wow how did you figure that out?

oh, in perfect conditions, your car could do a 13.1 in the 1/4 mile

damn looks like i got some more work to do i want to get in the 12s

20 horse off ain't bad, I couldn't have guessed that close. Dyno 2000 has flaws, some variables are basic, and it dosn't calculate inline engines very accurate at all ( has to do with the single runner ) which is where I need my calculations to be correct, it says within 7% accuracy, I'd like to find a person with a dyno'd engine and get the specs so I can varrify it's accuracy

Where is prattsville anyway Matt? I still got that extra grille, doors, hood, fenders, and all the 6-volt stuff you could want for your '51.
