Carb CFM help

Demon with 360 and similar build was getting 19-20 MPG on the highway with a 750DP. Car runs really good with the DP carb.

You could run either a 750 Vac or DP. I'd run a DP if you are planning on beating on it good.

The tune up: Initial, curve, carb settings will make a world of difference in how it runs.
