Installed 177s on 454 mags. They are inboard a cruiser so two issues;
1) there is no room for a traditional spark arrestor.
2) It has Holley 1050 and I am having trouble finding carburetor hats that fit

since the engines are under the floor in a rather warm engine room, I am planning on doing carburetor hats and hoses to pull in cooler air.

anyone got any hanging around I can buy?

thanks

Swamp

whats the diam of the carb flange.I have a couple short ones

Not near boat. They are holley 1050s that came on 525sc if that helps.

Dominator carbs are 7.25"

the 80s merc inboards had a sealed cast carb cover to a 4 or 5 maybe 6 inch hose inch hose so they could get outside air on inboard engines

Nobody else wants to ask what kind of cruiser are you putting huffers on?

7.25” thanks

Harley if I recall correctly...
