That's interesting info. There's certainly some solid merit's to doing it that way, I'm somewhat surprised to hear all those motor's were done the same way.. that being said it obviously works.
I wonder... why noone's really pushing anything done in that fashion (aftermarket block manufacturer's)
Must be a reason, is it a cost only issue, or is there a downside to that? Regardless, it's always nice to see a different approach.

Interesting. What do you guys do with the blocks when they're at that point.. when they need a sleeve. Do they get sold.. and if so, how much?
My thought is... maybe take one of those and send it to shawn @ va speed... have him sleeve it....
Take it to PM if need be.

why would you need a sleeve if it is LINERLESS. im sure there is a very good reason why they choose not to use one. remember....you do not have to ask what if if it will never happen

coated bores are not a new technology. I have two 1979 Yamaha SRX 440 snowmobiles that have coated bores. The part that sucks is that if you do have an engine failure (had a few) and it nicks the wall the whole thing needs to be re plated. Cant just be rehoned

It's certainly not new technology... but not something that you commonly see.
I'm interested in the finishing portin of the whole process. I am quite farmiliar with plating and how that works, I just wonder, what is done as far as finish machining on the plated surfaces. Plating is a neat technology... but has some limits. I doubt that when the liners are plated it's 100% consistant from one end to another, simply because that's the nature of the process.
PCB's for example, the outer edges always get plated more then the center of a backplane... for example.
