I've seen a kit similar to that listed on "the bay" a while back...Looks nice!!

If he hasn't retired by now you could call Dave Shadel at [link=http://www.pspec.com/]Performance Specialties[/link], it's his stuff.

I'm about 99.999999999% sure it's going to be the same design piston & liner that we all got with our orders within the last few years. I'm also sure Henry Nelson made the piston, liner and conrod for those kits too.

If you get the scoop please pass it along!! When you tear stuff apart if you can do some comparison that would be really kewl... [8D]

Unless you have a damaged AR I wouldn't think you would necessarily wanna run that kit in an AR...The AR has a really nice AAC piston/liner set-up from the factory. The porting actually looks very similar to Dave Shadel's YS liners. I haven't really sat down and done a head to head comparison but they are both radically different from the stock .61 LS...

Please keep us posted with your findings!!

Have Fun...
