I found a brand new 600cfm edelbroke carb for my boat I have a 455 olds stock with a mild cam do thinku think this would work...all I have ever owned is holly carbs?? O0
-
600 cfm is too small!
-
Well I looked up on the internet and a stock 455olds which is what mine is requires a 500cfm to a 650cfm so I thought it would be ok, ....but is there any problom with useing a edelbroke carb?? O0
-
If it's free and ready to run... I'd run it.

Not really, but where's the other one? :screwy:
Edelbrocks are, for lack of a better description, old Carter AFB and AFS designs. VERY different than the Holley in how it's tuned and worked with. Used to prefer them over the Holleys on street cars back in the day, because they can be tuned quite handily and even in a parking space at a "street meet".... :thumbup:.....They came quite often stock on dual quad offerings from GM, Ford and Chrysler back in the 60's.
You're problem is you're internet "requirement" is probably assuming daily street use from idle, many partial throttle situations and very RARE full throttle use. On a jet boat, complete opposite. You're going to be running the boat, idling out of the NWZ, cruising, at 3000-3500 rpm, and (hopefully) 5000 rpm at WOT far more often. There really only needs to be four throttle positions, idle, 1/2, 3/4 and WOT on these things........ :sly:.........but seen them work very well on jet boats! :thumbup:
The carb brand isn't the issue, it's the CFM. At 600, unless theres a second one on a dual quad or tunnel ram, blower, etc, you're leaving a LOT on the table at WOT, IMHO.
Then again, as BP said, "If it's free I'd run it!". At least for now and look for something a lot bigger, like an 800, 850 or a second 600 and dual quad intake.... :beer:

Q-Jet is a good carb, really, don't think you're gonna improve anything with the Edelbrock. But what comes to top of mind is your intake manifold........is it set up for a square bore carb or spread bore? ::) THAT could be another expense........forget adaptors, don't work well......

I think it is set up for square bore,it is same price for a rebuilt q-jet as for a brand new edelbroke carb O0

Did you look at the ebay link? Under $100 and you're on the water.

Q-jets are spread bore (small primary side and huge secondary side). I always had good luck with Q-jets after a bit of tinkering. And dont believe these are small carbs, there where versions capable of 750+ cfm. But they are the worlds ugliest carb if that matters.
