ITs a big cubic inch small block I bought from a member here on moparts.
R3 siamese block
Brodic M/C heads
roller cam
1050 dominator
4.25 stroke
4.125 bore
454 ci
Powerglide trans 1.80 gear
4.56 rear gear
Im hoping 9.50 when I finish sorting the combo out. I definetly need more gear due to the glide. So Im going down on the tire size and up on the Gear 5.14 ! And a radial 14x32 with a 101 roll out versus the 105 I have now.
