400 into 65 valiant

Moremopars4ed said

I don’t see much info about big blocks in older a-bodys. I’m going to attempt it. Anyone else? What do I need to look out for?
/6 about to come out. Have the trans Dapt motor mounts for 67 and up anticipating some fab work, going to see if the stock truck manifolds might work. Otherwise I think the Schumacher tri-y headers should work? Everything the sell is for 67 and up. Thanks

Hey, I'm doing what you're doing. I've got a 500" engine, tho. :D Do you mind if I join your thread?
My first and most pressing issue is engine mounts. I contacted Mancini who were selling engine mounts specifically foR B/RB engines in early-A but they're on back order, at least six months when I asked.
I don't mind fabricating my own but I don't know where to begin. Where is the engine suppose do sit with respect to the K-frame? I've got the K-frame out and the engine on a stand so I can measure freely and cut and weld as much as I want but where do I start?
