You just admitted on the last page to "just discovering" that the Stovebolt has 4 different housing bore sizes. You might take a hand hone that fits in a drill and call it align honing, but not many shops are going to gamble with a $2000+ honing mandrel that is designed to fit through all the housing bores at once and are the same size and chance tearing it up.
Thats 1 set for each bore size right?
Like one set for each different big rig rear ends, one set for sbc 283's one set or 235's plus all those pesky blue oval jobs?
Is that why some shops just flat out don't do some engines?
