And I have the 9" in my 57 now but the driveshaft is a couple inches too short.
I had to use different wheels.. some ford truck 15 x 5.5" steel wheels is all I had that had the correct spacing to keep the tires out of the fenders.
Sucks because i have some aluminum wheels that are 14 lbs lighter than the 15x7 gm rally wheels ..
Funny the 5.5" wide ford wheel is 2 lbs heavier than the 15x7 gm rally.
The 9" rear is also heavier than the GM rear i pulled out.
Getting there.. Going to have a shaft built.. probably next week before I get it.
I kind of want to change my cam also..
I have a 280H on a 110 LSA current cam is a 268H on a 112 LSA
The new cam should really wake it up..It ran 14.40 with the 268H and I think I can go an easy 13.50 with the 280H
