I am without my Service Manual and I was going to get my new pistons today, but I can't remember the stock bore size for the SC.

Help here would be AWESOME!

Thanks.

Trick,

Thanks for the quick response. You wouldn't happen to know if the stock 1990 SC rods were forged would you?

thanks

According to the documents I have, all Tbird rods are forged.

I've heard from others that the only thing that was forged on the 90 SC was just the crank. I always thought that the rods and pistons were cast...... :confused:

According to the specs from the literature on the front page, the SC rods are Forged.

But forged rods mean little in regards to strength. They are the weakest component in the SC lower end. That doesn't mean they are weak. Just the weakest part. I.E. they'll fail before the crankshaft or the pistons do.
