Cant seem to get this distrutor stabbed for the life of me. put it on tdc plenty of times, alinghned the oil pump shaft to the distributor,have the rotor pointing to the number 8 on the distributor houseing and number 1 cyl.with the electrical connector pointing to the firewall (little towards driver side)and it still acts like its 180 off for the upteen time. It does does that grumbleing start for 3 sec then dies with a puff of smoke out of the intake. Theres now way in the world to line up the white paint mark with the indent on the lower gear shaft,lines up perfect for the v6 part though.I thought the valves on the vortec dont get that 1 hole turn like the older 350s, they get a 1/4-1/2 turn after push rod dosent twist and i went the hole turn ( wasnt thinking and was in a hurry)but dont think thats the probalem but im leaning towards it in the back of my head though. But this thing is driving me crazy though. Cant hook up the scanner to adjust cam retard to zero i have to get it up to operating temp and above 1,000 rpm (timing is computer controlled).
