The Q Jet has been used in very small displacement motors to big blocks right from the factory. The Small primaries allow this. SMI (Sean Murphy) has his QJ's on cars for stock appearing drags class running in the 10 second range. For a street car the carb is hard if not impossible to beat. The comment that lets hear the down sides to QJ's..there really arent any expect they require more knowledge to rebuild and tune properly. Im with Tech...for a primary street car ...anywhere from 265 to 496 you cant beat one set up correctly. JMO.

Im sur eoyu have noticed the engine should run with what you have but definately isnt optimum for a low compression smog head engine with a stock stall speed and rear gears
