Carb size?
I have a 7.4L 300HP carbed motor. I'm changing the carb out, what size holley 4150 should I use and what size jets? Also changing to a air gap intake on recommendation from OSO. Thanks in advance!

look into barry grant sea demons, had very mixed results with holley marine carbs.
In fact I would recomend calling their tech line for a size recomendation.

thats like there fuel pumps are like 15 volts
The holley 4779 would be a good one,or the new version of it, or the BG speed demon,just order the j tubes or order them from Gary Williams carburetors,mississippi,he also sell carbs.
The BG seems cheaper than the Holleys,last time i shoped them.
A 4 corner idle will be better
