Got a friend that called me tonight and asked about alcohol fuel. He bought a race car that has a 355 Chevy and has no carb or distributor. i told him that I haven't messed w/ alcohol fuel cars but knew they are modified to run on alcohol. Do you still have to put a specific "alky" carb or can you just slap a Holley on it? I figure he could slap a Holley on it and run race fuel.

 

The gasket & seals need to be ethyl alcohol compatible. Jets need to be large(r). Metals in the system (lines, tank, castings, etc) should also be errosion resistant for long term use.

 

The carb is typically modified to alter the idle circuits, power valve metering, boosters, emulsion tubes & many other items.

For E85 you may be able to tweak a stock carb & get by, but for methanol, you better plan on getting a specific carb for that usage.

 

Ok,thanks for the input.
