After a day or so of reading, I’m leaning towards changing to an Edelbrock Performer intake with a new 500 CFM AVS2 Edelbrock carb. All new. Not “rebuilt 25 years ago by a professional “. Electric choke. Warranty. Sure, it may need some tuning but at least that doesn’t void a warranty. I’m tired of pig rich, inconsistent idle, and stalling when hot. I’m going to block off the heat riser passages in the heads/intake and run an insulator base gasket. 500 CFM will be plenty for a stock 350 Pontiac. Thanks all.
