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").

Cast crank slant six uses a different block, rods and crank than the forged crank slants. The rod and main journal are narrower. If using the 2.2 pistons make sure they are compatible with whatever rod you use. Not only on the pin location/rod length, but on whether the pistons are for floating pins or press fit pins. I wanted to run 2.2 non turbo flat top pistons, with K-1 rods. No can do. the rods are made for floating pins, and the piston are for press fit (no lock grooves). The 2.2 turbo pistons are for floating pins.
