Re: Engine Question...GenI or GenII !?
 

From the numbers it looks to be a Gen 1 Targetmaster. Gen 1's are anything up until 1987. Gen 1's use a 2 piece rear main seal. Whers as Gen 2's use a 1 piece that has a removable rear housing. A external oil seal. Where as the 2 piece is internal mounted in the crankshaft's rear main bearing cap.
