I've heard the same thing.....
So far, every crank that I have pulled from SC engines have been forged....
However, I have an 89 5-speed that I might be parting out....
If I am not mistaken, it has a build date of 2-89.....
I also have the engine out of Black Betty right now and it is up on the stand.....
It's an 89 with a build date of 4-89.....
I did a thorough search before posting and couldn't find anything definitive. I have the opportunity to pick up an early '89 SC. I'm only interested in the crank and block and would have to part out the rest of the car. It would not be worth the time and effort, for me, if it is not a forged crank. This is why I asked. I didn't mean to offend anyone in the process.
Where are you located.....
What's the color and condition of the interior and exterior.....
Got any pictures.....
