It had taken me some time to figure this out on my 87 Ramcharger. The 302's definately like less initial timing than motors w/o them. My beast likes 6* initial, 36* mechanical and total of 58* all in with vacuum advance.

Wow! What is your set up as far as cam, compression, and what octane? What rpm is that much timing all in at? Are you running EGR? My present 10:1 zero deck 318 begins with 675 boat anchors tries to get seriously hot in a short time at anything over 50 degrees total cruise timing, but I do have an intake gasket vacuum leak that I have yet to deal with.
