Cast Or Forged Cranks?

[SC UL8R1990]

Heard somewhere that SC's originally came with a cast crank, and developed alot of problems since it couldnt hold up to the power. When did they stop producing the cast cranks and switch to forged?

ive got a 90 SC, im a bit curious:eek:

Believe it or not, there is a FAQ entry for this. For members follow this link:

The original spec for the SC was a DURAcast crankshaft. A special casting process to give near to forged strength.

Ford was never able to get high enough yeild of quality product from their suppliers. Thus the switch to a Fully Forged part in production. It's possible that some very early 89 SC motors may have left the factory with Duracast cranks.
