Not sure what would be helpful but I'll start with this: It is a 1968 Dart GTS 340 (engine is all stock) , 727 Auto Trans and an 8-3/4" with 3.55 axle ratio. Carburetor is currently an Edelbrock AVS2 but plan on reinstalling the stock Carter AVS 4636. The AVS2 works fine but I did not feel it was much different than the original AVS so that is why I plan to go back. It currently has a Chrysler single point distributor but I have the original Prestolite dual point distributor which I would like to reinstall.
I have set the timing to factory specs but it pings under moderate load and acceleration. Backing off the timing helps some but does not completely eliminate the pinging.
Thanks for your interest; any comments/suggestions would be appreciated.
