We have seen balance jobs done buy magazines that have not been very close and guys get there kits and the piston box still has the factory seal on the box and rods are still in there sealed plastic wrap.
And 99.9% of engines kits sold are not clearanced on bothe ends of the rods or the pin bores in the pistons, We have seen guys bring in there rotators in because bearing issues to find nothing has been clearanced.
