5.9 360 Engine from a 2500 Ram for my 67 Dodge Dart

Yeah, there's only two choices that I know of with the Magnum bolt pattern. Magnum intakes bolts go vertical where LA are angled.

Since there's only 2, they charge what they want. The other choice is Professional Products CrossWind Intake Manifolds 55026

The M1 intake is a third choice but they aren't being made any longer and are even more $$.
