all factory sbc rods are forged. The pink rods were just shotpeened as your source says and double checked.

The 92 and 93 LT-1 featured forged rods that were shot peened at the rod bolt head and nut area for increased hardness. In 94, some LT-1 engines began to feature PM rods, with with PMs supposedly used in all LT-1 and LT-4 engines after that, but Ive seen some 96 LT-1 engines with forged rods.

Is he wrong? What are your sources?

That's the first time I've EVER heard someone mention forged rods in a stock LT1. Can anyone verify this?

Ok, I think he and I were thinking two different things. I'm thinking along the lines of aftemarket 4340 forged.
