Ok guys I’m in the decision making process with what motor I’m swapping into my ‘77 C10. It currently has a 250ci/Saginaw 3 speed in it, I have a 350 SBC and a 454 BBC that I can swap in(the six is neat but I want a V8). If I do the small block I’ll probably keep the 3 speed, but if I do the big block I want to swap in a SM465 as well.

Does anyone know for sure what tranny crossmember I’d need for the 4 speed? I have Googled my ass off and can’t find anything concrete. I know I’ll need the tail end tranny mount bracket thingy(won’t be using a 50’s/60’s bell housing mount obviously) for the tranny, I just don’t know what crossmember to use. Crossing my fingers I can reuse the one I have lol

Thanks!
