440 melt down

Foomaster said
Just going thru the watch threads I had and seen I had not put a solution to this problem. I did replace the carb gasket with a thicker one and problem solved. I know some car guys but they're Chevy/ford guys that have the eldelbrock carbs. They had same issues and pointed me in the gasket direction. I also have a buddy running the same carb with same problem, his problem is now fixed too.

Glad you reported back! My son's 340 had lots of vapor coming up out of the carb vents after a hot shutdown, indicating that it was nearing boiling, so we put in the Holley composite spacer and that fixed the vapor. That spacer is pretty thin, maybe 1/4" to 3/8", and that was good for his setup with already low hood-to-air cleaner spacing.
