While researching crate engines and actually having ordered a Chevy BB in the past, I don't understand why steel cranks can be so common or standard in Chevy engines, but when it comes to Fords, such as the FE's, the crate engines advertised always come with a cast iron crankshaft. Why is this? Even what I would consider an expensive engine, say $15,000-$20,000, the engine builder will supply a cast iron crankshaft. Steel would seem to be very cheap to just add as a standard to these engines. Thank you for your input.
