Is there a junkyard gem slant six combo?

'75(?) up use the 5/8" "peanut" plugs without drool tubes, I'd use that head to reduce potential oil leak points. to use the 198 rods, you'll probably need a forged crank bottom end. also to use those rods, you need pistons with a compression height in the 1.6" range. 2.2L chrysler pistons fit the bill and have the same size pins, but you'll need to bore it out, since the stock bore size on the 2.2L is 87.5mm (3.445").
