BB Engine question

[ChargingNemo]

Hey guys, I have a 383 big block naturally aspirated and carbureted (4 barrel) engine. I saw there were kits for Chevy, etc. that allowed for a more modern engine head to be used with the classic bottom end to still have that torque. Is there such a thing for Mopar engines or no? Would I have to go to a small block to take advantage of something like that? (the kits I saw were for a small block Chevy)

I did the 440 source on my 400, basically same block as your 383. Everything fits and bolts up like original but better flow and chamber shape as well as saving a bunch of weight. They are called stealth heads cause if you paint them the look original. You also get the hardened valve seats.

How much $$$$$$$$ ya got to spend????????????
I would NOT buy aftermarket heads & keep the engine size at 383. You will be disappointed for the money spent.
Best bang for the buck: buy the 440 crank update kit.

Lots of choice to do upgraded heads on a mopar. Like Geoff said, how much you wanna spend?

I take it you are wanting something like a g3 hemi head given the way the question was asked. I assume that means you saw a way to install ls heads on an old school Chevy. I don’t know of a way to do that on a mopar big block.

The small blocks had the magnum heads after a certain year. I don’t know that they would be better than an of the aftermarket heads though.

The aftermarket big block heads have better chambers than the originals. I don’t see why any of the choices would not accomplish what you are wanting. You can go pretty cheap and mild with the stealth heads, or go wild with the trickflow 270s.

Porter Racing Heads in VT is a great place to start as he can do all this stuff and isn’t locked into a certain brand. He also knows what is needed OOTB to set the heads up the right way. You can run stuff OOTB, but things like tight guides can be an issue, etc.
