Need another one from in the cab pointing at tach maybe?

Sure thing. Right after I swap the carb tomorrow morning.

......Next check I would do if not remediate... timing cover off, cam may be way advanced.

Would it run good up to 3200 if the cam was way advanced?
Thanks.

Yes it would...Problem here is that cam should have awesome torque right off idle. Advanced any, within reason, it should be even stronger right off idle. As in, no need to rev it up to make power. Advanced beyond the 105° ICL, power would fall off at higher RPM's BUT it shouldn't quit at 3,200 like it's doing. Unless cam timing is way out of whack.
When cams are WAY OFF, the factory timing mark, on the balancer, usually doesn't match up or work right with where timing has to be set for the engine to run its best.

I had a similar issue, and it ended up being a bad coil. The engine would stop revving at 3500-4000 rpm. Thanks to this forum, I was able to diagnose it properly.

Good luck with this. Lots of good ideas here from knowledgable people.

I’ve run into the same at the track too with coils and modules in the stock car days. Both don’t like excessive heat. Burnt thru cheap rotors were an issue also, but different symptoms.
