Piston and connecting rod?
Piston and connecting rod? I came across these Scat 6.125 H beam 4340 rods. Anyone here use these? Are these comparable to Eagle rods? I'm looking to build a strong bottom end to handle a 200 shot. I also read somewhere on here that SBC rods have an offset and LS1s are on center. I am assuming they mean the wrist pin. I see Diamond offers LS1 pistons for the 6.125 rods. Are they made to accomodate this offset? If not could I still use them?

The offset is definitely not good. If the rod is not centered on the pin (at the piston) it will side-load the piston and cause wear on the cylinder walls nearest the pin location. The engines that use an offset rod are designed so that the big-end offset actually centers the rod on the piston pin. Hope this line drawing survives being posted. It is a little exaggerated, but hopefully it will get the point across.
As far as which rods to use; Carillo, Lunati, HTC or one of the others that use American forgings with a centered design will be fine.
