What is the difference as far as driveability goes between the q-jet and "regular" edebrock carbs? My K20 is a dd, and not a wheeler. Never will be. So the operating angle of the carb isn't an issue. I'm just curious what differences I'd notice with a standard square bore Edelbrock carb over the q-jet. I have an Edelbrock 1904 q-jet on my 454 now, and it's all wrong. Runs waaaaay fat, no choke etc. Trying to decide if I should get the thing rebuilt/adjusted for my motor, or pick up one of the square bores and give it a shot. Engine is a mild built 454. Performer 2-0 intake, Comp cams extreme 4x4 .544/.564 int./exh. 270/278 dur. Stock peanut port heads. Otherwise a stock 50k miles, Goodwrench 454. Manifolds till I can afford the headers. (I know thats choking the shiiit out of the cam.) Anyways...Other than that, just 2 40 series delta flow flowmasters.
