Holley holley 75009 3217

From what I have found it is a marine carb but for some reason I can't find the cfm of it or really any other info.

Whats the difference between a marine carb and an carb for a vehicle?

Can i use this carb on my pickup?

The guy wants $80 for it, if i bought it I'd get a rebuild kit for it and clean it up like crazy before even attempting to run it.

Marine carburetors are set up richer than street carbs and typically richer than performance carbs.
Marine engines are always loaded - there is no such thing "cruise" like when you are on the freeway. Cruise in a boat is pushing a lot of water and the engine is under a load. The carburetors are set up for that load. The jets are bigger, the power valve has larger ports and the PVCR is usually larger than an equivalent street carb. I have never tried to tune a marine carb for the street but I have modified a few performance carbs for boats. I think you have your work cut out for you on this one.
