Made some changes... need input
Previous setup:
1965 Nova chassis car ladder bar 2870lbs
540BBC 870hp est, turbo 400, Dana 60 4.56 gear, 33x16.5x15 107 1/4 rollout. Ran 9.00-9.04 in a three day period. 60' times were 1.30-1.31 and crossed the stripe at 7200.
Changed rear tire to a 32x16x15 102 1/2 rollout. Hoping for a little better 60' times and 74-7500 at the stripe to be up in the power a little better. What do you guys think it will do?
