To solve your pinging, either reduce your initial, limit your mechanical, or adjust your vacuum advances. Your engine is no different than any other when it comes to timing.
I dont agree with adjusting the mechanical. If you limit your mechanical you're never going to get the TOTAL timing youd need if you do a wide open throttle run (WOT). I think the only thing that needs correcting is the vac advance limiting. If you take anything away from the mechanical advance you'll never get proper TOTAL TIMING which is 36'
