I think that you WILL get into the 9's with ease! My 408ci small block Koffel's Place engine with a 904 transmission, 8 3/4 rear end with 4.86 gears, and 33X16X15 slicks; I am in the 9.79 -9.83 range. Here is one of my ET slips from the Norwalk Chrysler Classic.

60' _ 1.328
330' _ 3.936
660' _ 6.165
MPH _ 109.77
1000 _ 8.119
1320 _ 9.797
MPH _ 133.63

GOOD LUCK!
