512 Build

Starting a 512 build. So far, of the 3-400 blocks I have, 2 are .060 over and 1 is .030 over. So will get them sonic checked to see which one has the thickest cyl walls and go from there. One of the .060 over blocks has very little wear, was a truck block, and the pistons are like new. ICON has pistons in .033, 040 and .060 oversize. IC823-040 is the one I like. I can get 13 to 1 C Ratio with that flat top piston :usflag:
