Resurfacing deck, affect on cylinder bores

I'm not going to mention who did the work because I really think my block machining does not really represent the work they normally do. I will say that they are a major Moper shop with alot of satisfied racers out there. I will be traveling in the area of the shop next month and will stop by and talk to them about this.

I'm working with a guy in Sycamore, IL now and he is pretty good. He setup his machine square to under .001", mounted the block and checked it and realy found some odd numbers. Each bank on the block is tapered the same but in totally opposite directions?? Not only that but the odd side is quite abit higher than the even. The only thing we can figure is that the block was indicated using the factory machine work and just cleaned :scratch: Got a little concerned that maybe the line hone was bad but it checked out ok. I'll be picking up the block tomorrow and will post the final results.

I agree with you on the benefits of good and accurate machine work, we work to tolerances under .0001" at work and I'm very picky. I'm just glad I checked my block out and didn't assume. Lesson learned!
