that sounds like the ultimate camshaft to run, the prop I am running has adjustable pitch carbon fiber blades and works well on this chevy thing....on a dodge it will be a powerhouse pretty much sums up why I was looking for an industrial engine, parts, or information. the chevy guy's that have airboats pretty much rule the waters since they are so plentiful, i don't hae the money they have but I have the dodge parts and really a dodge has a stronger block webbing and a bigger thrust bearing than a chevy small block, they all whine that ya gotta have a four bolt main block and the only thing I see is that a torrington style bearing would benifit any direct drive boat or adding a second thrust bearing would promote longevity
I have looked in the manual for my combine and cannot find torque or HP ratings but it does say governed RPM is 2800 under load and no load at 2875 RPM.
