400 into 65 valiant
The crank centerline for a SB early A is actually offset 5/8" to the passenger side - according to TTI anyway. The difference between pass and driver's side frame rail to crank centerline measurements are twice that, obviously (1-1/4"). Mine landed at 9/16" to the pass side (1-1/8" total).
I did what most folks do and bolted up the transmission mount to locate the engine and transmission front-back. Though you could put it however far back/forward you wanted depending on how much extra work you want to do.
