I have a freshly rebuilt chevy 350 with a MSD 8360 distribuator and a lunati cam with a 489-504 lift. It will start but runs rough and won`t idle. I can`t time it because when it is running my timming lite when hooked on #1 wire is flashing slow. It dosen`t matter which wire I hook on to it is all the same. can you help? thank you

I would try to time it in by ear the best I could to try to get it to idle then unplug the caving advance bring the engine up to about 2,000 rpms then your light will flash faster. Also is the carb tuned in rite are the valve adjust correctly more info on the engine would help

Change the springs in the distributor to a blue one, and a light silver one.

Disconnect the vacuum advance and adjust the timing until it idles.

Then connect your timing light to the #1 plug wire (front wire on drivers side).

With the engine at idle set the timing to 16 degrees BTDC . Raise the rpm and watch the timing. The total timing will be about 36 degrees at 3000 rpm.

Get a Crane Limiter Plate (#99619-1) and limit the vacuum advance to about 10 degrees.

Get online and do a search on recurving distributors and you'll see how to do all this.
