I saw this on an engine forum
DS, to give you an idea, I have seen 4-71's rated from 82 to 325 horsepower.
Usually they run in the 160-200 range, but marine applications with the DDEC chips are getting 300+ horsepower out of them.
...and another referenced an inclined or pancaked 4-71

and/or with turbo charging
