Offset SBC Rods in an LS2? Can I use Gen-I rods in a LS2? Any issues with the centerline offset? Anybody using them now? Just checking before I spend money.
Thanks Frank

Looking for a 6.200" Rods. Limited choice with on-center LSX's but the Gen-I's open many possibilities... Just wanting to make sure there was no known issues with using Gen-I rods in the LS2 block.

FYI, You can run Eagle 6.300 SBC rods with an off the shelf (402-408 stroker) piston. You can come up with these with just about any dish size you want. I used Diamond -15cc dish in mine, they ended up .005 in the hole with no decking and my SCR is 8.75 with a 72 cc head and .040 cometics.

Who's pistons? The pin boss spacing will tell whether you can run those rods or not and the rods pin end width.

The Gen-I and Gen-III share the same rod journal dimensions and there are no issues running off set rods on a Gen-III so long as you have the clearance between the pin boss to keep true vertical rod alignment under the piston.
