I get a bit of pinging as well. Always run premium gas and my timing
seems to be on. Running electronic ignition, 5 speed tranny with a
stock Ambo rear. Pings awfully easy in 5th unless I'm really on the
gas. I'm going to try a new set of advance springs just for the heck
of it.

Anybody think its the mismatched tranny and rear drive that causing me
problems in 5th? To low of rpm's?
