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, andOriginally posted by EIonJess

With 225whp how much horsepower would you say you were putting out at the crank? I was thinking like 275-280???theoreticallythat should give you crank hp.
