If i remember those are hypereutectic right?

Nothing wrong with em but you need to make sure there's correct sidewall clarence and the rings are set up correctly and they will last for years but if there not clearenced right they will fail. There not as strong as a forged set but are fine for a warmed over build.

Agreed, the KB's need a lot of ring gap due to expansion, the specs are on their site.

..........Anybody else have input on these......thanks........kim........

If you are trying to achieve a specific and consistant quench, the reverse dome pistons usually take a little effort to set up.

Ran 11.50's at 117Mph 7000rpm in a SBF with KB hypers. As long as the machine shop goes by the KB spec for clearance you should be ok. As stated they need a big ring gap, if i recall I had a .026 gap.

As long as the tune isn't lean and timing advance isn't crazy pretty tough to break them in N/A form.
