Gotta disagree! One of the most common problems that people have with the Edelbrock and AFB Carbs is excess fuel pressure,both Tech Inspector and myself have brought this point up many times over on other sites.The first thing people will is "I only have a stock fuel pump" it is not uncommon for stock pumps to push 7-8 psi.If you run one of these carbs, GET A REGULATOR! and set it at 4.5-5 psi no more.
