There is some good information in this thread ....

The problem is without pictures we don't even know if you have a Holley or not.

Yup! GTG, mostly, work it over, or have it done, and have fun with it. Will perform MORE than just fine, although the Double Pumper and Dominator guys will tear me up on that. Unless you're splitting hairs, AKA, racing or a Frankenstein-ish balls out engine build like Marc or Nordie, 4160's are just fine.

Don't have Moo's old carbs handy at the moment to compare and tell if that is the Marine version or not. Couple other 3310's I have here tell me it is NOT. I'm a steadfast beleiver in Marine carbs on all boats, enclosed engine or not. I understand budgets, but I also have good reason behind it. On the other hand, MOST of these guys run, and have run for decades, street carbs with no problems.......... ;D
