Re: VINTAGE CHAMP CAR REPLICA BUILD

I just got back from a trip out to the American Museum of Speed in Lincoln NE. I will post some pertinent pictures of details I saw. I learned a lot. I also met with another gentleman who is building a car similar to mine but with a '41 Lincoln V12 complete with exceedingly rare speed equipment.

My experience with aluminum intakes is that you do not need water under the intake. To totally eliminate carb icing you will need to run warm AIR ducted from your exhaust manifold (header?) to the carb inlet, similar to a stock air cleaner.

The 2100s have a larger mounting surface and bolt pattern than the 2GC. Both are good carbs readily available. Linkage on the 2GC may be easier as some have a push-me-pull-U linkage so you can pull from the top or bottom whichever works easier.

Early points distributor caps used 7 mm wires. You will need 7-to-8 mm adapters to use the 8 mm wires with that cap. Or adapt a later model rotor and cap to your points distributor.

A Rochester 2GC carb is probably a better choice if you plan to just use the existing stock intake hogged out.

I have had no problems with the stock drive quill on a hi-volume pump. The EFI head is actually less prone to detonation when used with the correct spark schedule. It burns faster resulting in less end gas tendency to knock. But it requires less spark advance (a GOOD THING) than the carbed head.
