And not being one to take another persons work for granted, I popped a couple top rings down in few random bores. Checked 3 places top to bottom, .026 gap on the money.

Now I'm going to go test my luck blasting this TBC off. Then order some new rings to file down again. Which I haven't personally done since 1993..

NC, I ran down to Raleigh to check out an LT5 engine my buddy at Crawford Racing is doing. Little CANBUS and L5P throttle body hacking side project.

Cool, my reg cab is at Mayhem in Raleigh for head work and tuning. Bunch of performance shops up that way. You head this way much?

No that's only second time I've been out to Raleigh area. It's a good haul out there off of I77 that I normally travel.

Next time your in Raleigh and staying drive on down to Wilmington, it's about 2 hours. This place is unique, Lots of cool history, downtown is on Cape Fear river, midtown has college and then there's 3 beaches that are each much diffrent from the other. Fishing is great almost year round offshore and inshore as well, if I'm not buried in a console I'll show you around.

Cool will do.

Gave the glass beater a shot. No luck with fine material. Cleans the soot off nicely, but just smoothes out rough edges on the coating.

So guess I'll be calling up Swain Tech again tomorrow to explain how I'm not risking 5k worth of pistons to remove their F-up's. They said they have a way to safely remove it, so will hope they do. . .

Could you not just remove it from the side of the pistons and leave the top intact? Or are you worried it will flake off and do more damage?

Seems to me if it could resist the blasting maybe it should stay

This set only has couple hours running time. While the other set with 8-10 hours showed much more lifting on the top. So I would like to remove it all and then polish the tops as I had good luck with that approach on previous build on std race cast pistons.
