They're fine for a mid-level engine, but for the money, Scat's 4340 I-beam is far superior and now available in 6.700 AND 6.800 (previously only 6.700).

Those 4340 forged rods are about the same quality as all the other off-shore stuff in the marketplace however, they do use their own USA manufactured 8640 aerospace grade bolt; (190,000 psi tensile strength is in-between ARP 8620 and ARP 2000).

I've noticed a lot of the off shore brand stuff. I think u might invest in this kit. It's just for a bracket dragster. I can post details if need be.

I bought a set for a small block stroker and was surprised that the weights and sizing were spot on. The  PC salesman DID caution me that the bolt should be replaced by "real ARP" bolts which I did before using. The finish could have been better as there were still some visible machining marks but not detrimental to longevity.

EDIT I am NOT endorsing PC stuff. MANY guys I know have had bad experiences with their products. I had my local machinist / balanciing guy thoroughly check them and both of us were surprised at the dimensional accuracy. I think I got lucky.
