Mopar intake manifold

either carb, set up correctly, will be a very good unit. problem is there are people that can overhaul/rebuild them but very few know how to make them work. in s/s racing, set up properly they are better than a holley. i will run 1 on my carbed magnum on the cast iron intake and attempt to wring out a lot of mpg. there are 3 diff cfm. 750, 800, and the hard to find 840.
