My 350 skylark currently has a 750 Edelbrock with manual choke. It runs ok. There is a small stumble during cruise when you tip back into the throttle. I have tuned with a wide band and I can't get rid of it, no matter what I do. I chose to have Cliff R. build a Q-jet for me. I should have it by the end of the month. The Edelbrock runs, but I think that the Q-jet will outperform it in every aspect. My .02.
