Carb Spacer? Edelbrock w/ 318

The set up I used on my daily driver for years and years and years was 1/2" phenolic carburetor spacer (composite wood like spacer) Eddy carb, 1" Eddy black plastic spacer on the top of the carb and a drop base aircleaner. The extra 1 1/2" taken up by the 2 spacers was canceled out by the drop base aircleaner. You need the 1" black spacer on top of the carb for the air cleaner base to clear your linkage.
It worked great, took care of any heat/fuel issues and acted like a mild high rise intake.
