L72 Trip to machine shop

[shor]

The cylinders have never been bored before and Nick, my machinist, recommended .030 over for the rebuild. I told Nick that I really didn't want to go .030 over and that I wanted to keep the block as factory original as possible. He said that we could easily go .005 over without a problem, if I wanted to order custom made pistons. The pistons would be expensive and the lead time was uncertain(summer months!!). After thinking about it, and employing the 24 hour rule(wait 24 hours before doing anything), Nick came up with an idea. We will keep the standard bore and just power hone the cylinders. We are going to order TRW replacement pistons, standard size, and send them to be teflon coated. The coating adds about .004 to the pistons so that combined with the new rings will be a great fit. I want to use the same pistons but Nick insists we get new ones, there is some pitting and other age issues with the original pistons(trust you master engine builder, I was told!)Sound like a plan?? I will keep you updated as we progress.
