Summit Carbs

What the Cheif said is also my take on them. I also ran a 4011 spreadbore 650 unit once. While it did run OK, I felt it could have been better myself. I didn't exp. any heat soak, it didn't impress me to much and thus left the car promtly. I favored the AVS much more myself.

The carb series was short lived by Holley and they stopped making it. I feel that it was ill-marketed to start with. The operation and performance of the carb was good. But as far as performance is concerned, step up. It would be worth the wait to do so.
