Ok, so whats the deal with Edelbrock carbs (I'm pretty sure I opened up a can of worms with this one)? In most threads Holley is carb of choice, just difficult to dial in, all the talk though. Q Jets seem when properly tuned they run hard, and easily maintained. What about Edelbrocks? Just curious, cause I'm in the middle of getting her fired up, and possible carb change. I bought a marine Edelbrock after reading reviews (amazon) and cost, to replace a Q jet (was that a mistake?). I just don't see any threads about Edelbrock carbs. Is there an obvious reason for that? With other members suggestions I'm installing a pressure regulator along with pressure gauge and inline fuel filters. Sorry for the ignorance folks I'm definitely learning a lot from this site and as I go along.
Set up, Carrera 202XR open bow, Marine power 454 sport pac 330hp (I think), all stock original parts, AT pump with A impeller and inducer rebuilt by GS Marine last season.     

I have no boat experience with them, However, I messed with one on a 350 in a car, and it out performed a holley that was set up for a BBC/berk. Secondary transition was tricky to get right on the eddy. Should work fine on a stock 330 combo, with some tuning.

the best advise i can give you is too down load the manual from edelbrock. and stock up on those stupid rods!  had one of those carbs on a blazer. hated that carb till i got it right, then never had to think about it again.
