Did you recurve the distributor ... shorten the mechanical advance .. before advancing it that far, Stock Chrysler distributors , even those sold thru Direct Connection and Mopar Performance, have 30 degrees of mechanical advance so it's not a wonder why it pings at higher RPM.


Yeah, several people have said that. I don't know if it pings at high rpm, because when I advance it at all, it pings at lower rpm, so I back off the throttle. Clearly, I have some tuning to do.


Put the timing back to stock spec , 5BTDC till you get the distributor recurved. 4secs flat has an easy kit to limit mechanical advance.

running up my post count some more .
