float bowl

[rgalajda]

Can anyone tell me the purpose of these?

[RFSPHPbb]

look like bowl stuffers to me. reduces the volume of the bowl for increased emissions control. or something like that.

Probably reduces fuel volume for road racing, less slosh on turns.

I've seen those phenolic spacers in at least a half-dozen original GM-installed Holleys. For as many as I've seen, I have reason to believe they were part of the GM OEM Holley configuration package. I can see no purpose for them other than to reduce fuel volume.

I had a 30k-mile 71 LT-1 that had them. All the ink stamped numbers were still on the carb, and it was the factory-installed carb.
