Just tore my q jet off few weeks ago. Had a brand holley 670 cfm street avendger sitting on a brand new manifold for about 6 mounths. Doing a ls motor swap and adding a carb. So i installed it and man did it make it better to drive. I just get in and push the throttle down 1/4 way to reset the electric choke and release it and tap the key and my old wore out sbc springs to life even at like 30 degres out side. The q jet took atleast 3 tryes to even get to run for a few seconds. Maybe if its all stock put a 570 on it. Also see way better low end from new carb. Still need to tune it some.
