4.3 carb Holley

[jay127]

I have rebuilt my 95 4.3 omc. I added vortec heads and a vortec 4 barrel intake. I've seen that I need a 4160 Holley carb but have no idea how many cfms I should go with. Any help would be appreciated.

They come in 450 and 600, right? Holley Performance Marine 4 Bbl Performance Products

I've only heard of guys running the 600. Looks like the 0-80492 is set up for your 4.3.
