I was reading up a little more on the Q-jet and it say's the primary venturi's only come in two sizes 1 3/32" and 1 7/32" also says the factory sells carbs based on application not CFM but they are all "loosely" rated around 750 to 800. Seems awful huge!! The V-6 and the 305 both seem like good cannidates. I think I have seen one on a V-6 before but I can't think of where. Maybe on a older S-10 pick up??
