I have two 600’s on mine. You can jet them down depending on the vacuum reading

jetting down might be that case sometimes but i have had an engine with too big of a carb on it and he actually had to jet up (richer) because the signal to the carb wasnt strong enough to pull the correct amount of fuel. Just make sure that you have some way to check AFR before changing jets

Yeah I ran to 650 spread fours on a 440 duel quad tunnel ram and absolutely loved it but a much different application from truck to Boat
