Carb recommendations for my 340

QJ is a spreadbore like the TQ. Same bolt pattern. You need to check fitment to the intake to make sure all the passages in the carb base are covered & that linkages do not foul etc....
My son has an 85 Dodge Truck with a 360 that came from the factory with a QJ. Think QJ's were cheap and Ma Mopar was savin' a few bucko's.
