I bet that MH has a Dodge 440 with a ThermoQuad carb. Probably all plugged up with old fuel residue. Mike: Isnt there a club devoted to the M300-600 chassis? They must be able to get brake parts somewhere. Lots of parts on those units were discontinued 20 years ago. The 440-3 uses a special thermostat. Using a regular Dodge stat will cause severe overheating. The heads are different. The exhaust manifolds are giant heat sinks that melt plug wires. But awesome power.
