Guesses on ET?
Guesses on ET?
I have a 327 block bored 20 over, 350 crank, 882 heads milled to 70 cc, 4.10 gears, 600 cfm carb, T5 trans in a 91 RS. Im gonna run it this spring. What kind of ET will it have ? This same motor was in a 65 OLDS 442 w/ 3.08 gears, (heavy car and same heads had 78 CC at the time) and ran 15.3 with a TH400.
Thats it? its a summit Street/strip cam, i dont have #'s on it. no dyno info either. i should pick up at least a 1.5 with the 4.10, get more with milled heads, then get even more with a lighter car.

If you don't like the answer then wait until the track opens and go and see exactly what it will do. A guess is just a guess. No 2 cars are identical so no one will know exactly what your will do without hard data.
How much does the car weigh?
How much dyno rear wheel HP does it have?
Give me that data and I'll tell you what the car should run. Other than that, it's all a guess.
