Any experience from anyone? I mocked one up the other day with a crank, piston, and rod and it appears to not need any clearancing is this normal? It has .100 clearance between the rod and block min. at all locations in all 8 holes.

They build em every day... So long as you have clearence between the rod and the panrails & bottom of cylinders, you will be fine...

Yeah that's where I have a ton o clearance at. My first attempt at a "stroker". Just don't want to fuck something up, by missing something. I was really expecting to have to grind the bottom of the cylinders for more relief. Thanks for the reply
