400 into 65 valiant

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.

I only know about '67-up, but engines in those are offset 1-1/2" to the passenger side as well. Are they centered in the early A's?
