pyro: I have a holley and the injectors pluged up on me after a year. I modified the TB and installed the Rochester upper unit and it worked fine except for the off idle throttle plate sticking problem it had. I finaly put a 4.3L TBI unit on, end of problems. I have made several Fuel Regulators adjustable but there dosent seem to be any difference in performance on my 2.8L with 180K miles.
Good Luck
