Wow, I had no idea. Is it a one-piece main seal block and drilled for OE-type roller cam and lifters?
I'm still curious why the bore would be +.040". I know some engine suppliers go out to +.060", but that's out of necessity and not a generally a good idea. At the shop I worked for, we would not go any more than +.030". Maybe the Blueprint blocks have thicker cylinder walls than GM blocks.???
