73abodie don't be a smartaleck owning mopar since probably before you were born I know better than to crank on a mopar distributor but a dumb chevy guy wouldn't and yes I tried to reset it but since he turned it both ways I was not able to get it back to where it was initially set and the popping and pinging only happens under WOT...and yes I did put it under a light but what good is that without knowing just where to set this thing up at so I was wondering if anyone might have a similar setup with their 440 and could tell me what the appropriate setting was instead of snyde remarks like yours 73abodieadd
