my truck has a rebuilt 355 with mild cam high compression heads and an edelbrock open throat intake with a 3 inth spacer on it. ( my redneck version of A highrise haha) i have a 1406 edelbrock 600cfm on it now and it runs really ritch. the carbs only 2 years old but it sat with gas in it on my project car. i have the air fuel screews turned out 1 1/2 turns and the choke is set right. someone told me it could be gummed up and a float or somethings stuck inside causing it to run rich. i also have a freshly rebuilt 500 cfm edelbrock sittin on my bench. will this be enough for my motor or should i tear my 600 apart and find the problem? thanks

Maybe float needles sticking? Why not "pop the lid" and see if it's a float issue? Would be easy to correct.

I don't think it would "kill your motor" so to speak. If the carb is in good shape, it should do you just fine. It might run out of breath at high RPM's, but it should be good for driving. I'd put it on there till you can get the 600 fixed. I'd bet that 80% of people who hop up their engines are running over-carbed anyway.
