We have done our job, now we can take it aprat again, pack it all up and return to the machine shop to let them perform the rest of thier job. This is going great, we feel good about our engine, we are confidant that things are fitting right, and while it was here and apart I even checked on the machine shops work and measured the pistons and bores. The bores are 4.029" and the skirts on the KB pistons are 4.0275 - 4.028. The tops of the pistons at the top ring land are tapered to 4.003. Everything feels nice. Time to lug the pile of parts back to the shop!
