Slant 6 on a V8 k member?

K member aside, you will need a passenger car oil pan (center sump) and matching oil pickup. You will need a slant six specific transmission (different bell housing than V8's). I don't recall whether the 82 trucks were computerized ignition or just used the 'standard' electronic ignition. If the truck engine uses a computer (behind the battery or on the air cleaner) you will need to get something that will work with the 72 car- either points or electronic distributor. If the truck engine is a 2-bbl (Super Six) that will be a bonus, but you will need the auto trans kick down linkage (specific to Super Six) if you go that route.
