While viewing this site I saw the Bill Laney cast a manifold that appears to be engineered well. Hot rodding is all about making something work. Seems Bill Laney stepped up to the plate for us sb Mopar guys.
I still would have to spend time doing the port work on my adaptor plates, intake and water. No big deal really, just scribe the Mopar gasket pattern on one side and the chevy pattern on the other and whittle away at it, of course an air grinder in one hand and a beer in the other. Drill and tap the mounting bolts. And weld in a valley pan.
