I think I have a 6 vein off the 318 that I can swap on and see if it changes.
My concern with backing my timing off is how am I supposed to tune the car for peak performance? I have no detonation now, which means I can probably run a few more degrees on pump gas and squeek a bit more power out of the new motor.
If you back off on the timing and your heating problems goes away then you have an idea on what could be causing the problem. You can always move the timing back, right?? One step at a time.
