LT-1 Replacement Carb Suggestion

[VintageMusclecar]

Gary;

That is a strange problem, esp. being intermittent. Does it ever do this just while driving, or is it only after you've jumped on it? Have you tried jumping on it a little bit before the engine is completely up to full temp, and if so, did it do it then? (trying to determine if it's 100% heat-related)

It almost sounds like you have an intermittent issue with either a/the float(s) sticking, or needle & seat(s) on the way out, but being heat related is throwing me off a little bit.

Do you know anyone with a good carb that you could borrow? Even a generic 3310 would suffice as a temporary mule to see if that isolates the problem.
