skip white HEI timing issues

no i put my compression tester in #1 cylinder and waited for compression to come through the tube that way i knew i wasnt on 6 instead of 1 and afterward i out a screw driver in the hole to find the highest point of the piston so i should have it right

Buy a TDC tool from Proform : where I would start. No guarantee on compression tests or leakdown testers here. You really need ,to find actual TDC & check that harmonic balancer ring. As for import stuff:It works, My standard go to is an OEM distributor, non digital MSD box. Used the Crane HI-6, nice stuff.
