Holley 2bbl on 305

[Hvymtl]

What holly 2 BBL model was used on a 1999 GM marine 305? Is it a 300 CFM or a 500 (75004-1 is model?))? Will any 2bbl Holley rebuild kit work, appears in catalogs that there is only one?? Thanks!!

Any Holley kit should work, they usually come with the parts and such for any CFM rating in that shape/configuration.
The CFM might depend on the setup of the engine, how much power it was rated at from the factory. More power is going to need more CFMs

That's the same model # as the carb on my 5.7 litre. It's a 500 cfm( if flow rated like a 4bbl, the cfm would be about 350 )
