Eagle hemi carburate?

Well if it's useable as is, the money used to refresh the 383(assuming it needs it), could go to all the swap parts. And still have some left over probably. I would keep it injected. You would be happier with it I think. Hotwireauto.com can set you up with a very reasonably priced plug n play harness and computer. I've done these both ways, carb or injected. The Eagles play nicer injected. They have the VVT and short runner intake you can take advantage of staying electronic.
