QSB5.9 Marine
 

I was looking at the Cummins MerCruiser web site and wonder if anyone has done any research to find out if some of the marine engine parts (injector, cam) would work in a CR engine like what was done in the past with the 12 valves. They seem to have some beefy engines for marine apps. Up to 474 HP. :o

Or a turbo and a tuner, that would put you over 474.
