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.
