I tried to install this guy over the weekend. Found that the fuel inlet was 4" too far right to make a good tubing adjustment, the vacuum inlet for the brakes was a size to small and the last straw was that I would have to scrap the old throttle hold down bracket and buy something from a hot rod supply house.
So I check all the screws on the Q-Jet and installed a new manifold gasket, never would think that a Q-Jet could idle, accelerate and run so good once it was tight.
Should I return the Holley or give it another try.

Stick with the Q-Jet. It'll run better anyway and get more mpg.
