Today I was told with the build I am doing on my 460 I will have to step up from a 750 to an 850. He recommended the Holley 4781c and can get me a good deal on it (cheaper than summit anyway). However my boat is wired for electric choke and these are manual. Do I just cap off the wires? Also my engine is under a hatch and these are not marine carbs. Is that a big deal? Auto engines are technically under a hatch also......
