Guys,

I have a holley 6520 on my GLH. I've read that the Mopar Performance non feedback carb was really a Holley 5220 with different jets. The Dodge 2.2 performance book suggests changing the jets to 191/346.

Anyway, I have an old 6520 that needs a rebuild and I plan to put the 191/345 jets from the MP kit in it. I've removed the feedback sensor from the 6520 carb too. Is there a plate (maybe from an old 5220) that will go in place of the sensor and wires? I removed them and I believe there will be a significant vacuum leak where the wires used to be.

Any help with this? Should I just dig into my pocket for a rebuilt 5220? Or maybe a Weber? (Webers cost a mint.)

Will the performance gains - with the Holley 5220 - be worth it?

Thanks,
Mike D'Antonio

NOOOOOO you just cant pull the feed back sol... it is the power valve but electronically controlled. the BEST carb to use for your application is a Weber DGV series....I've had luck using an older Pinto 5200 carb.

Thanks for your reply......Can I replace the electonically controlled power valve with one from a 5220?
With the Weber EGV will there be any linkage mods?
The webers are so expensive......

You can't replace the O2 solenoid with a power valve, the bowl and air horn castings are different. If you want a reasonably cheap non-feedback carb, look in a junkyard for a 2.2L minivan, 85-87 I think. They use a vacuum secondary with out the O2 solenoid, and it is a drop on. Now all you have to worry about is the ignition and alternator control. I am using a 1980 1.7L distributor shaft, cut to fit a pre-1986 2.2 housing and the HEP and cap and rotor for the 1980 1.7L. This gives me a dual advance non-computer distributor that can run either the 1980 amplifier or most aftermarket systems. Alternator, either use a 1984 Bosch or keep the stock carbureted firewall mounted regulator. Good luck with it!
