I thought a 502 is the same block as 454 the 8.1 vortex is a entirely diff motor. Unless I am missing something everything will bolt right up to a 502. Just has longer stroke. With some fab work a shift linkage is doable. Might come from behind as noted. As far as gear ratio. I am planning on almost 2x torque that it has now so really depends on speed. Most of these gear boxes are .3 overdrive. I think I have a 373 gear set. It may only run in 4th a lot of the time or 5th on the 6 speed. A vacuum gauge can tell you the best gear to be in.
