slant 6 swap

A little squirt of ATF in each hole to help lube the rings and seal. You may also want to run a second battery for the ignition so it is not affected by starter draw. Basically just hotwire to the ballast from the other battery. Have you checked to see how much slack is in the timing chain by moving the crank both directions and seeing how much movement you have before the distributor moves? Possibly a slipped timing chain?
