Hardblock?

My engine builder wanted to get a standard bore 340 block and sleeve it down to the 273 size. If I wanted to build a killer 273, then I'd do that but I want to keep the costs down. It quickly looked like a $20k engine if he was going to build it. I don't think an R3 block would be that much better since it would still need to be sleeved down.

It looks like I should have started a separate thread on the 273. I thought the hardblock info would carry over between the brands, but it looks like things got corn-fused.
