i know it once had dual four barrells in the early sixities

 

Chrysler Corp. did not make one on a production vehicle.

You can get one now from MOPAR PERFORMANCE. The part number is:

P4529055 [six pack manifold for 383, 400 etc.] call your nearest MOPAR distributor.

 

I think barry grant has a six pak setup for the 361-400. I believe its called "Six-Shooter".

 

Like Omaha said, Factory no, aftermarket yes. You can still find them both new and on e-bay and other sources for used parts.

 

you could go dual fours
it was available in the real early sixties

 

They didnt do a factory set up but Il say this, for the same amount of money you can run a single 4 bbl super charger on that 383 and have about 80 horse vrs. the 20 your get from a 6bbl. If i was building a street car id go that route, theyre not that hard to work on, but the 6bbl is cooler, your call.

 

I know the carb setup is kinda pricey to buy new; but you can get it.

 

it is pretty pricey

 

i wish i knew you were looking my grandfather in TN just sold an intake and 3 2bbl holley carbs for a 400 he had in a dart at some point in time for 300 bucks. not bad since brand new performance 2bbls are 300 each
