Piston I D

Post #8 asks the key question. If these used pistons really are 4.058" OD near the bottom of the skirt, and the Badgers for which the block was bored were .001-.002" larger, then these KB's will be too loose. KB's like this are hypereutectics and are set at a tight clearance, not the larger clearance like a forged piston would use. Most machine shops never bore 'til they have the pistons in-hand, just in case they find a variation in piston diameter.

Not trying to 'queer the deal' but hopefully you guys will work something out 'just in case' these end up a tad too small for your block's bores.
