350 to 454 swap
Ok so Im taking my 350 out of my 83 long bed and shoveling in a 502 and was curious as to the driveshaft situation and tranny crossmember. Ive heard there differences that I need to address and just not certain I am having a professional perform the transplant but want to stay a step ahead to keep from holding him up. Any thoughts? or recommendations?

Just bolt it in. Tranny and driveshaft will remain the same. You'll need to rework your exhaust but that's about it.

I swaped a 305 to a 454 ,it just dropped in. already had a 700r. All the front parts(ac/ps/pb/alt/ needed new brackets as the bolt different place on the 454.

You might wanna beef up the rest of the driveline like the trans and if you have a 10 bolt go a 12 bolt or bigger.
