Just remember, New doesn't mean good. While I agree the Chinese rods are made of far superior material than the OE rods, and are forged. The machining processes need to be checked for size on each and every rod, big and small ends. Although Eagle stuff is much improved, we are still seeing some that are on the very edge of the tolerance range and even outside by .0001"-.0002". This means some are over .001", larger than the minimum. Have a set of Eagle press pin rods for a Chevy in class. 4 out of 8 had .0005-.0006" press fit. That just isn't enough, even on a .927 " pin. Had to put oversize pins in that set. Not a big deal but please check everything and expect some new parts will need work before installing. Just checked a "balanced rotating assembly" for another Chevy Tuesday. It was out 6 grams on the front and 16 grams on the rear. It would have worked OK like that but it certainly wasn't "precision balanced". No reason to expect Pontiac stuff to be any better.
