Is that a 600 edelbrock or a 750?Dont think they have a 650.If it is a 750 throw that POS in the trash.600 will work fine same with an 800.This is not an edelbrock bashing,I have used 600 and 800's with great results.I had a 750 on a hot 360 had every problem you've described and then some.Started doing some reasearch and come to find out these carbs are CRAP.I would borrow another carb if you can and see if your problem goes away.If not fuel system somewhere
You are right. Its a 1406 which is the 600 cfm model, NOT A 650 which doesn't exist. If I had another carb to try, I would do that. But I don't. I am using a 1 inch spacer between carb and stock steel intake manifold to try and eliminate gas perking. I can't go much higher. The air cleaner will be hitting against the hood.
