I believe it would be a reasonable estimate to add 60 hp to our whp in order to get crank hp for our cars. If you want to get technical, take the 227 stock crank hp, and divide it by the stock 167 whp. You get a multiplier of 1.36. So, you can multiply whp by 1.36, and theoretically that should give you crank hp.Originally posted by EIonJess
With 225whp how much horsepower would you say you were putting out at the crank? I was thinking like 275-280???
