Eagle / rpm rods

The H beams arent bad, and stand up pretty well. The I beams depnding on manufacturer are a better material, but the finish machining can leave a little to be desired..(I havent used the I beams...but builders I know have, and the ones that check, find inconsistancies). The 6 pac rods are heavy, and beefy, but, use the same smaee rod bolts..SO strength wise, they are not as strong as an LY rod. (the bolts will fail first..) You can use better bolts, but they are still very heavy. LY rods will hold 500-500hp easy, but should be replaced beyond that.
