The new Street Demon carbs are a great carb. I have installed several and all have done a good job. They are a spread bore design that will fit both spread bore AND square bore intakes. Available in 625 and 750 CFMs.
I read the designer of the Street Demon carburetor worked for Carter back in the 60s and 70s. He took the best attributes of the Thermoquad, the AFB and the Rochester Quadrajet when he designed the Street Demon. Cant go wrong with a new carburetor with a revamped design.
Forgot the Ford VV carbs? Nothing inherently superior in a revamped carb. It all depends on the design, new is not always better.
