I have a nice QF 1050-AN carb that makes good power. It gives up a little bit to the Dominator but some of that could be due to the intake manifold. Are you going to run an adapter on your M1 4500 or are you going to switch intake manifolds?

Have you run the Dominator yet? That was a three circuit correct? It will be a lot more streetable if you just plug the intermediate circuit and run it as a two circuit. The intermediate circuit doesn't work on a street car since it goes super rich at part throttle.

If you plug the intermediate circuit and get the Dominator jetted correctly it will run on the street. Use a power valve and lean out the main jets. You'll also want to run plenty of ignition advance. If you do that the Dominator should work okay.
