Edelbrock Performer vs Edelbrock RPM Airgap

I messed with the ignition timing a little last summer, that helped.
I cant tell you what my initial timing is set at, cause I thing the outer ring on my vibration damper has slipped a little or something, If you try to use the mark on the ring to set the timing, its way retarded.
I set it by ear last summer by using this method. Disconnected and plugged the vacume line. Advance it till it pinged a little under moderate acceleration. Then started backing it off a little at a time till no pinging.
Then reconnected the vacume hose, drove it, pinged, then backed off the adjustment that's inside the vacume canister by putting an allen wrench in through the hole where the vacume line goes. Backed that off a little at a time till no more pinging.

So not sure what its actually set at, but its running good. I don't have a dialback timing light so I have no way of knowing what my total timing is, or at what rpm its "all in".
Really don't know much about changing advance curves, etc. Its all greek to me.



Also, the car has the Mopar Perf, electronic ignition on it.

As far as the carb, when I first put this engine together , it did have the common, off idle hesitation. I rejetted the carb, changed out some metering rods/springs, etc.
Which got rid of hesitation and got it jetted down a little for my 5000 ft elevation in Colorado. But I think it's still a little rich, that's why I want to get the wideband 02 gauge so I can get the carb set just right.

p.s., the cam was installed "straight up" I did not degree it.

I'd consider a converter change, but just a little higher than stock stall.
And I wont be changing gears. I don't race the car, its just a cruiser, and 90% of my driving is on the highway
at 60mph, so don't want to go with a steeper gear.
