I have a ‘65 coupe with a ‘91 5.0 that has an edelbrock carb and pertronix distributor and coil. It’s been running fine the last couple years from when I did the engine swap.
Recently it started getting a small random miss, and under harder acceleration it seems like Almost the entire engine is missing. (Sounds like a rev limiter except it’s at like 3k). Under normal (light) acceleration it is fine until just over 3k it gets a very small miss. But once I get on it, the whole thing faceplants and starts missing like crazy. Any ideas?

Have you checked the usual culprit, ignition wires, spark plugs? If so and all looks well, Sounds like a lean condition. I don’t know the type of carb you’re using, never had an Edelbrock carb, but increasing the throttle opening without fuel would give you that condition.
