have to do is protect your reputation with quality work and consistently
build winners. For those that may not know, all out race engines come with no warranty.

#1 - Yes, based on the thoughts of mine and several others, the prudent method is a maximum overbore of 0.060 and then sleeve back to 3.875" on a used cylinder block. The only other caveat is the cylinder walls still need to be more than 5MM or 0.200" when finished resizing at 0.060. That basically allows room for 0.020" of rust or pitting damage to the inside of the block.
#2 - Yep.
