67 commando 273 issue

fireguyfire said
So I picked up the suggested edelbrock 9266 spacer and the bolt pattern on my AFB and factory intake are quite different.
I could maybe butcher this spacer but it won’t be ideal just the way the correct gasket overlaps the 9266 for comparison.
Am I missing something?

My buddy who is a retired mechanic said to just make one out of 1/2” plywood as that is the way they used to do it all the time in the old days, but I’m a little leery about putting a flammable item where all of the fuel and air comes together.

An old racer friend of mine had wood spacers on his tunnel ram with no issues. In fact this one is wood fiber and has a dual bolt pattern. THis one is Edelbrock 8723.
Yes, the carb base is smaller on the early smaller cfm carbs. Apparently the spacer didn't have double holes drilled like the carb bases are. The bypass fuel filter pictured above will help if you are having vapor lock while the engine is running butt as soon as the engine is shut off there is no flow and the gas can still boil in the carb.
