A buddy just bought a 350cu crate engine for his PU. It runs at 65 degrees BTDC at an idel.

Piston at TDC ( checked with a dial indicator ) the timing mark on the balancer reads 0. Timing mark at 2 o clock. I had this issue once before on another car and it was the distributoe fazing, took it apart and moved the bottom gear 180* and the problem was fixed. On his truck we fazed the distributor and nothing, installed a new ignition system and distributor and nothing.
It still reads 65* at idel.

HELP

What ignition is it. MSD, HEI, MSD HEI etc..Does it have a msd box on it??

If thats a msd distributor check the the polarity on the pick up. I've seen them that far off before. You can force the plug-in backward for a quick check, and then swap the pins around if that corrects it.
