Pinging

Yup. I do agree I must do something. It's a real drag to spend cash for improvements (upgrades) just to end up with more problems. (One step foreward, and two back).
As I stated, if done by ear at idle and with (max) vacume then back off a tad she pings pretty bad, however performance isn't too bad. Maybe it could better! If I retard it just a tad to get rid of the ping she stumbles badly (out of time).
BTW, This is a problem I had some time ago that I posted. I rermarked TDC #1 compression. However, once the motor is running with timing light on, I have trouble finding TDC. If I turn the dist to try to get 8*-10* BTDC she wants to stall. I thought my damper was screwed, but then why would TDC line up on the scale.
So yah, somethings out to lunch. I agee with re-curving but to send something out just to find I still have a problem else where after spending more money will piss me off even more. I'm going to try the canister thing first as "what" can I loose.
