Whats your gear ratio?
i will be installing a 8 3/4 rear with 323 gears.i would like to change these to 355 or 391 but im not sure when.This stuff gets exspensive.I want good tork off the line,spin tires when i want. I will be also installing a 727 tranny.I would much rather have a 904 i think , but im getting a good deal. I have decided not to put to much into this motor in hopes of upgrading to the 360/390 hp crate motor someday.
