400/450 stroker....Cheap parts, lotta work.

KB put a generous fly cut in these 251 pistons of .264" deep and 2.360" in diameter. When I checked the piston to valve clearance during the overlap events we have .278" clearance on the intake and .296" on the exhaust. Wow, looks like some of the big solid roller cams we have on the shelf would have a shot at working in this engine. Naw, scratch that idea. Think street engine.
