OK, I tore it all down. I have aligned the crank shaft sprocket (the original marks on the main pulley were off, so I made new ones). The timing belt and new Delta cam are aligned. The distributor is pointin to the number 4 plug wire on the cap or the 10 o'clock position as described by everyone. I have the mark on the distributor shaft straight up toward the cam. It is an AMC head I installed about 30K miles ago. My question is, where is this mark on the cylinder head that I am supposed to align the distrubutor up with? From what I have told you does it sound like its correct?
