This is an R-302 block and already modified for clearance. We are touching the crank throws when the piston is a bottom dead center. The Wiesco pistons used last time had less piston skirt so I believe we are going to do a little grinding with a template we will make from those pistons. This is not a kit. Everything is custom and high dollar. So far we have ran this combo into the 8.50 range at over 160MPH with a 3350lb. car. If we could just make it hold together a little longer this time
