Ok, just to let you know my truck has a HEI distrubutor with EST (Electronic spark timing) with ESC (Electronic spark control). There is no crankshaft sensor, and the PCM has stored spark advance tables.
I rotated the crank pulley until I felt pressure, then rotated it backwards until the rotor moved. I made a mark near the timing plate on the dampner and rotated it forward until the rotor moved again and made a mark. It is about 8.5 degrees.
I checked the distrubutor gears to the camshaft by twisitng the shaft of the distrubutor. It moved just slightly about a half degree.
I do not understand physics well but when a chain that loose is running, can it get off and hurt performance (low power), or can the pcm tables compensate?
