Brian,
I don't remember when I saw your car if the carb is mounted front to back or side to side. There has been a lot of opinions on why or why not to mount 4 barrels sideways on those engines.
If you remember my 250 I am running the Offy with an Edelbrock 500 on it sideways and I've had zero problems.
If you can't get the problem resolved after checking for the usual vacuum leaks, etc give me a call and we can kick it around over the phone or I will even take a ride down and we might be able to solve it together.
