I got the 350HO crate motor from GM. Came with darn near everything, including a Holley 600. It runs great in the Jimmy. That is, when it's on flat ground. As many of you know, Holley's street carbs aren't the best at angles and this one is no different. Floods pretty easily. So, I've heard of some attaching a valve that limits max flow so that the Hollys won't flood. Switch it on when you get offroad and flooding is pretty much done away with. Is this a decent idea, or should I just go with a quadrajet and be done with it? Next question, how much should I expect to pay for a good/rebuilt QJ? I have access to a 750, but I don't know how much it will cost and even if that's a good match for this engine (I think it would be fine). What do you guys think? Recommendations are needed and appreciated! Thanks.
