The best part, this is a 2nd 318LA swap into a wheeled payloader. The 1st one went into an old Allis Chalmers TL12 when the little Hercules diesel over-revved itself after something went goofy in the injector pump while I ran in for more beer.
this would appear to confirm a 69 motor (as told earlier about the road runner) or at least that's pre-70 LA waterpump, and what appears to pulley and dampener. if there is a timing tab cast into the cover on the pass side it's 68/9.
