crankshafts for Kents

where does one find a specification (in objectively verifiable terms) for "cast steel" AND a drawing showing "original Ford Kent and SCCA dimensions" ?? at this point it's a reliability curiosity as there's no horsepower to be found in homogenous crankshafts with the same profile and weight.
