it doesn't work that way. the blower fits between the carb and the intake.


I think some of the B&M blowers (probably Eaton also) bolt in place of the carb as they have the same bolt patterns as a standard holley, carter or edelbrock carb so you can use your existing 4 barrell manifold and then the carb bolts on top. But i am not 100% sure if this is correct, so you might need a special intake for this type of blower.
the ones they use on the modern cars are all designed for fuel injected applications so most of them are of the blow thru design (that is they blow air into the manifold as opposed to a draw thru application that sucks air thru a carb first then into the engine). but they are of course all designed for the particular manufacture and engine so would be a lot harder to modify to fit your application.
