Got my 235 block down at the machine shop, and the machinist mic'd it out and said he'd have to bore it .060 oversize. The truck had run ok prior to pulling the engine and had compression of 105-110 in 4 of the cylinders, 1 cylinder was 90-95 and one was 60. The one at 60 had a nice crack in the head and a sticky exhaust valve. The engine wasn't blowing smoke or not anything noticable, but I'm wondering if the machinist is ?
By the way the block had never been bored and currently has standard size piston and rings, does it make sense that if could run ok, but need to be bored from standard to .060 ? :rolleyes:
Thanks
Kevin
