The Holley has vacuum secondaries, so I was told that it would only draw what it needs. I heard great things about Q-jets, but the Holley is in hand, so that should do for now. Thanks for all this information and encouragement. This should be a interesting project, and a bigger engine will definitely be a priority in the future. Out of curiosity, do most of you guys still use points? I have the computer HEI from the 305, but no computer, so no advance. Right now I am using the points from the 383. With an engine this small with low rpm, would there be any benefit in using the HEI? Thanks again for all this great info.
