Went to Billy after using his dad for a few engines in the past. Billy a very high attention to detail threshold and I was very impressed. He bored and honed a Dart 351w block for me and all the bores were exactly 4.060, not 4.0605, not 4.0603 no 4.060. Every bore was 4.060 all the way down the bore, no discernable taper. He took a little bit longer than originally planned, but it is something you should expect from any machine shop, heck some places in the area are 3-6 months out. Hopefully I can keep using Billy for future builds. Dont be nervous taking your stuff to Billy, prices are reasonable and the work is A+.
