I like the Edelbrock carbs on a street car, sometimes then can be a real bear to get calibrated correctly, but the stepped metering rods, springs, and main jets when dialed in correctly really work good on the street. Very smooth in the transition circuit and part throttle operation. Takes a bit of reading and some time to get it right but once they're set they stay tuned very well. They don't like a lot of fuel pressure, 4 psi is plenty. Make sure you get a good seal on that QJet manifold to the carb base, doesn't take much of a vacuum leak at all to mess up everything!!!!
