Re: Swapping out 258 for a 360 ..Advice
I'm finishing this same swap right now. Invest in some good quality motor mounts. It will make your job easier. I got mine from M.O.R.E. You'll also need at least a 3-core radiator for the V-8, along with the proper shroud. I changed my clutch to an 11" from the 10 1/2" stock. I also changed the tranny mounts to polyurethane to help keep it from twisting. I don't know anything about modifying the input shafts. Did I miss something?
It's more work than you think to do it right, but it's worth it in the end!
