From the often quoted "Rebuilding the LT1" article:
Not sure how accurate the info is, but most of what is in the article seems to be correct.
RODS
350 - The original LT1 came with regular forged 350 rods, that were shot peened for localized hardness under the head of the bolt and nut. Powdered metal rods were phased in for the Corvette around 1994 and used in all of the LT1 engines by 1995. GM made the change because the powdered metal rods were cheaper to make and were much stronger than the GM high performance "pink" rods. In fact, they are supposed to be good for up to 450 hp. They are machined at the parting line so they can be reconditioned.

i always thought the pink rods were an upgrade from the stockers. i just bought a rotating assembly from a friend that had pink rods in it and he put down 615rwhp with no problems.
im going to use them in a nitrous motor so i may change them anyways.
