Which intake manifold
How do you plan on using the car? Any other mods? Stick or auto? Rear gear? Etc? The 4412 is kind of big for street diving on a close to stock engine. The barrels are large, and don't have much air velocity at low RPM, so drivability suffers. For a almost stock engine use the Mopar 2bbl manifold, and a smaller 2bbl carb. That manifold did have some issues with porous welds, but if you paint it with epoxy paint, that will cure any possible problems.
