Not too big of an upgrade, Saves you a few pounds over the iron manifold. I believe the 69' RR came through with 650 Carter AVS's, sort of like the AFB, but the primary barrels are SLIGHTLY smaller than the secondary barrels. Not to be confused with the Carter Thermoquad!! All in all, an easy carb to tune and maintain. A good rebuild/ jetting adjustment (for todays crappy gas) and some ignition timing changes, you're off and runnin'!!!

I'm just being logical, not talking about the experience of course. we got also 6packs on 340s ( 1000 cfms ), true just the center is the pumper With a Charger born in Chrysler assembly plant in Valencia, Venezuela

That is why you can run those big carbs on little engines. Holleys don't do that. "The only thing to do for triumph of evil is for good men to do nothing" "NUNQUAM NON PARATUS!"

True. BUT, you would have to improve the breathing habits of the motor (headwork, headers, cam and intake).

That is why you can run those big carbs on little engines. Holleys don't do that. Six packs are an example too. Carters are more forgiving then mechanical secondary Holleys. Although, the kick off the line will be stronger with the DP. Vac sec Holleys run strong too, if set right. AVS carbs are almost foolproof.
