Yea I have a 600 holley 1850 now. I am gonna run it. I would like to upgrade eventually. But that is not on the top of my priorities! Number one on the priority list is getting all the machine work planned out and done.

Well hell yeah! Throw that thing on there. They are great carburetors. You might find it small, then again it might be perfect.
