400 into 65 valiant

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?

According to TTI, the crankshaft centerline should be 4-3/4" from the K-frame for small blocks. I would use that as a good starting point when locating a big block. Footnote #39

There's some info on where I located the BB in my 66 in this thread: Early A Big Block And Motor Plate

Good to see people still stuffing big blocks in these little early A's! Someone asked "why?" LOL I say WHY NOT?!
