Thanks everyone. I forgot to mention this is a street car. I think anything steeper than 4.10's will be to much for the street. It's a 750 Performance carb. Thanks again.





Well, we narrowed it down to mid 11's - high 13's

A better carb would show cheap and easy gains. One thing that would really be a nice change (but not cheap) would be a 904 transmission with a low gear set. The 4.10's with 29" tires will allow you to cruze on the highway comfortably but the low gear set will launch like you had 4:56's. In addition to significant gains from better 60' times, you will pick up a tenth or two just from the improved efficiency of the 904.

How the car runs will depend alot on the condition of the shortblock and heads. "Ported heads" can mean many things.

I just bought a Quick flow 1050 carb. That should be plenty to feed it. I'm hoping for 11.90's or low 12's. Thanks everyone.
