We start with an OEM Ford 2.3LSOHC 1pc rear sealcrankshaft, and grind it .010" undersize on the main journals and rod journals except for the offset ground cranks which have even smaller rod journals Then we have the crank heat treated We do this to our OEM crankshafts to increase the toughness of the crank and extend the life under the added stress of high-RPM, or upgraded turbo!
No high-rpm or high-horsepower engine should be assembled without a heat treatedor billet crank!
*** We do offer un-heat treated cranks like our competitors for $100 less than our heat-treated cranks, but we don't recommend them for anything but a factory stock rebuild Anyhigh-performance engine, and ALL race enginesshould really have a heat treated crank!***
