Bore prep for short skirt pistons
I am building a 393 clevo, and I am wondering if the bore needs any extra prep when using these short skirt pistons. I was under the impression that a small chamfer on the bottom of the bore was benificial.
I have just picked up my block from the machine shop for dummy assembly and noticed that they havent done this chamfer. Is it needed or not?
I also notice a slight chamfer on the top of the bores edge. Is this normal? I am hoping they havent chamfered the wrong end of the bore
