These kits are available for the different series of Holley Carburetors that we offer. The Demon carburetors used the same basic shapes and dimensions as the Holley carburetors along with some of the gaskets and internals. Speedway no longer offer Demon kits and with the demise of Barry Grant you may be limited to what is useable in the Holley kits.

The Pro Form is a 4150 style body so you would want to use a 427371544 or 42737485
