Hi guys,
I'm rebuilding my '94 454 king cobra after years of valve problems and a stolen Holley 750. I pulled the motor and had the block cleand, and bored .030 over (due to pitting) Running the original crank (balanced) with a pro-speed domed piston and I-beam rod setup. The original peanut port heads went to the scrap yard and replaced with an Edelbrock Marine large oval port aluminum set on top of a .510 lift procomp roller cam.
I'm getting ready to install Scorpion's Marine endurance roller rockers and an Edelbrock Air Gap 2-0 intake manifold.
I am trying to decide on a carb for this I/O setup. The factory Holley 750 went missing while at the storage yard a couple years ago so I need to replace it with another. Looking at Quickfuel/Holley 4150 750cfm, Edelbrock 1410 750cfm or other highly reputable setup. Electric choke, Mechanical Secondary is what the boat came with originally.
Any thoughts on this? I know the throttle and clutch linkages are sensitive on these OMCs.

whatever you choose needs to be marine compliant. 750 CFM if it's a stockish build
