Rite on ill forget the spray with this motor and I shouldnt have a problem with consealing weight due to the fact that most impalas are a helluva lot heavier than mine. But anyway ya its being built for grudge racing.

Well just to give you something to compare to, here is my combo.

'65 Nova, 540BBC 12.6 comp Reher- Morrison cam .808int .765ex, Turbo 400, Dana 60 4.56, Hughes 9" conv 5800 stall, 2870lbs with me in it.
Has run a best of 8.99@ 149. Crosses the stripe at 72-7300. I run a 33x16.5 tire now thinking of going to a little shorter tire on the next set.

Just something to think about.

Probably to a 14x32 or 14.5 x32 got to check the rollout #'s

Well B I was thinking 250-300 more at the stripe. I really need to get the thing on a dyno and find out what it makes and at what rpm.

dyno's are a good thing...to tune..not all the numbers they put out are realistic in a car,,,but you know this already...I think your doing the right thing...put a 32 on it and check the Roll out 1st to make sure they are shorter then what you have and run it....nothing will tell you more then the seat of your pants and The ET/MPH just back up what you feel,,,when it comes to gearing situations anyway..all the 4 and 6 speeds I ever owned and even a few automatic's (without electronics) I always shifted with what My a$$ was feeling...and that was normally just before the car nosed over... 8)
