[6x6er]

Hello, I have a 1991 366 on propane with an AT545 allison tranny inserted into a 1956 army 6X6. It runs great as the engine was replaced in the school bus just before I had purchased it and swapped it out. I was hopeing for more power/torque capabilities from this stock engine. A buddy of mine suggested installing an M112 Eaton blower and maintain a 7# boost. Sound great but also sound like a lot of modification to the intake. The blowers can be purchased cheap but definitely not a bolt on option. I am not very familiar with the parts family, heads, intakes, cams, etc, for this engine as I am with the small block chevy's. Any ideas of what I could do to this engine to obtain hopefully more torque as I am pushing heavy weight from time to time, it has a dump box on it.
