And the large spline Will take at least 430hp, and with 325/50-15DRs, and with a GV shifted WOT, and with Centerforce II. Right up until you forget which tranny is in the car this week, and bang it into "4th". Boom. Its bye-bye O/D.
The o/d is STRICTLY for cruising.I broke a couple of those.
To Alpha; About the only parts that will interchange between those two is the synchronizer assemblies. And certain tail-housings. Oh and the needle bearings. And the Rev gear/pin. And the oil-flinger.And the cluster washers.I think I got it all?Anyway the point is; nothing in the gear-train interchanges. Nothing
To the OP; I put the B-body trans in my S-clone. Very little trouble besides the obvious.A wee bit of grinding on the tailhouse to clear the X-member. And a custom shifter mount.And a custom driveshaft.
I mounted my shifter about 8 or more inches back from the factory A-body location and high enough to be able to insert the top shifter pivot/mtg bolt from inside the cabin. Then I fabbed a custom set of longer,sturdier rods.This put the short-stick shifter between the buckets, very near mid-thigh. Perfect. No more missed shifts.Ever!Of course I had to also fab a new shifter hump, and cut the carpet.
