The carb will not drown the engine. Size of carb has NOTHING to do with it. QUOTE]
Well, I'm sorry, but I have to disagree. An 1150 Dominator, no matter what "state of tune", will not function correctly on a slant 6. Likewise, I doubt a 390cfm Holley will work on a 600 in. blown Hemi.
They make different size carbs for different size engines and applications. Otherwise, Holley/Edelbrock etc would only have to make 1 carburetor size... 2000cfm...and it would fit all engines.
Chrysler used 800cfm carbs right from the factory on <150HP smogger 318's that never topped 4000RPM. I saw a car with a little 302 engine running a 950cfm HP-series Holley...and theory be damned, it ran great!
