OK picture this... an older Chevy 400 small block with a 493 lift cam, roller rockers high rise aluminum intake, holly 750 4 barrel double pumper, 4x14" air cleaner, exhaust headers and stock heads. Can anyone tell what kind of performance I can get out of this setup?

 

Jon,
The answer to your question is both obvious and ambiguous.
With those aftermarkets, it's certainly going to be more powerful than a stock engine. What you do with gear ratios, tires and tuning, will slant your vehicles ability toward quarter mile, top end or going off road. One thing more is that I'd keep pretty close to a gas station. :wink:

 

It's a 1984 Monte Carlo set up for circle track racing in the bomber class. It has a 273 rear end with a mini spool. 3" off set wheels on the right side running 235 70 15 and straight up wheels on the left side with 245 75 15. Going to put an MSD 6AL ignition box on as well.

 

Are you running on a Clockwise track ?
Why do you have your larger wheels on the left side ?
