I have a Haynes book on Holley carbs. I am just doing my rebuild, but it seems pretty good so far. If you would like you could let me know the numbers and I could ID it to get you started or at least let you know what model number you have.
the way you ID it is with the number stamped on the front of the airhorn but I couldnt find a single thing on 3745.. you might want to double check that and post all the numbers, there are probably a couple.. (on the airhorn)

I'm no expert, but Ive got the holley carburetor book by Dave emanual. It's pretty good and Ive learned a lot. According to the book (Pg. 64), The 4700 series (4776-4781) are aftermarket carbs designed primarily for race applications. I have a 4779 by the way, and will likely change it for a vacuum operated secondary unit. This carb is known to run and idle rich. From the book it looks like its not so easy to rejet and it for sure sucks down the gas and fouls plugs. Book says yours is a 700cfm mine a 750.
