need help picking crank I was going to order the crank today and wasn't exactly sure what I needed. I ordered an iron ls 6.0 block off of summit and it says gen 3-4. I was going to order my crank from callies and wasn't sure which reluctor wheel I need, any help would be appreciated, thanks.

What exactly are you trying to build here? A stroker crank from Callie’s won’t cost any more than a standard stroke from Callie’s. You going for a 408” build? All forged bottom end? 6.098” or 6.125” rods? Rod length affects piston selection, as well as which cylinder head you want to run, meaning an ls3 head will require a different valve relief, than a cathedral head due to radial clearance. Lots to think about here, so hopefully you have a plan. It’s often cheaper to purchase the rotating assembly as a unit, is why I’m asking all of this.
