It depends on what year carb but mostly they are the same.  SHould work on a car I would think?

Marine carbs are set up to run with VERY restrictive air cleaners.

Years ago I bought a carb and intake from a Marine 340 to use on my 360. It ran terribly. If I placed both hands over the carb while running and blocked off most of the air, it smoothed right out and ran great. I made a restricter plate out of the back piece of a Chevy starter with lots of holes drilled in it and used it until I could find a better carb.

Oh, to be 16 again........

so are you saying it may run lean. did you try differnt jets? or did nothing help but the plate?

Nothing helped but the plate. Your carb could be different that the one I had though. It was so long ago that I do not even remember what brand it was.
