Re: Quadrajet metering rods
Q-Jets are emissions carbs and are designed to run on the EXACT engine it originally came on, but they can be modified to run on any engine. You are going to have to make some changes to the idle tubes, down channel restrictions, idle mixture screw holes, idle bypass air, main jet, upper and lower air bleeds and primary and secondary rods. I know this sounds like a lot, but these mods are easy to do and once they're done, the carb will out perform ANY carb on the street. I made the switch from an Edelbrock Thunder AVS 650 to a Q-Jet and have never looked back. It delivers more power/torque, better fuel economy and a better idle. The 1st thing people are going to asy is, "ditch the Q-Jet and get a Holley", but IMO, Holley's can't hold a stick to a properly tuned Q-Jet, both in power and MPG.
As far as a rod to suggest, we are going to need to know your specs. Cam size, etc. The carb settings are very specific depending on engine specs. You are going to need a full set of numbered drill bits(1-60 & 61-80).
