440 timing pinging and popping thru exaust

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

Here's how I read the post: You have a timing issue creating the problems you have. You do not know what the distributor you have in there has for advances. You are not sure how that particular distributor can be adjusted (or if it can be). You have not stated what kind of distributor is in it... So my advice was to figure out how it adjusts, and then set the timing curve. Turning both ways is what you do before crossing a street - not how you adjust or actually set up a timing curve. My impression is the replacement distributor is not set up like your old one. Hence the inability to make it run like the old one did. Provide more details on the distributor you put in, and tell us what the timing is set up to now, and we can help you fix it. Possible appropriate settings were communicated but we have to know where you're starting from to tell yyou how to get there.
