If you bought the mopar performance distributor it already has the performance curve.(light weight springs)and your all set.
Timing should not advance any more past 2200 rpms or so.
Set your timing with the timing light and your off.
Start at 32 degrees on you timing light and lock the distributor.
You use the 0 on the timing tab to time the car.
You most likely know this ,but i don't like to leave any info. out.
If you don't think it's having any detination problems then go to 34 degrees.
Check a plug if 34 total is feeling good and make sure your not going to lean.
What was your timing at when you got pinging up hills???
The mopar performance book is part #4876826 by larry shepard
I think they may have a new one out,but i am not sure.
