Currently have a freshly built SCAT 347 Stroker with GT40 3 bar heads, and an e303 cam. Car keeps wanting to stall and seems to be running super rich. What is a good spot to set the timing to? I’ve seen a couple of people
say 12 degrees BTDC but i’m not sure. Any help will be appreciated.

That should be fine. The general range for best performance is 10-14 degrees. Poor timing is not likely the reason the engine won't run.

The engine runs, just kind of rough and stalls occasionally. Once you crank it once or twice after stalling, it stays running and runs pretty good for the most part.

Anything 10-14 should run fine really.

If if you ran closer to 0 degrees or ATC the engine should still run, albeit very rich and probably a tad on the hot side

Please answer the spout and codes questions.

Help me create the "Surging Idle Checklist"

Updated 26-Oct-2019 to clarify creeping idle RPM increase as the car is being driven. Many of you are familiar with the "Cranks OK, but No Start Checklist for Fuel Injected Mustangs" checklist and the No Crank Checklist. They are very effective in finding and eliminating the problems by use of...

It may run better but I bet you ain't 'fixed' it.
the checklist will give you the confidence that it actually is running it's best.
