What about going from a mostly stock 904 to a rollerized 727 behind a small block? If the 727 had all aluminum and light weight stuff and the 904 didn't what would be faster?
I had my 727 rollerized, aluminum drum, etc, etc, and replaced a stockish 727 with this new trick one on consecutive weekends..i saw exactly zero difference ET wise.
A 904 with most often be about 1.5 tenths quicker than a 727
That would've had me hot! 904 here! Stock rebuild. Flex Band, 4 clutches. Shift kit, 500 horse, 500 torque, mid 11's in a 3550 lb car with no issues.
