These piston pieces can get themselves wedged between the piston and the block when the engine is running, and can cause the block to get a hairline crack in that cylinder bore. It is rare but I've seen it happen two or three times back at the old shop. Bob
Mine was one of the rare ones I guess...figures!! LOL.

I'ved never been a fan of pot luck I mean pump gas. When I started modding my car I always ran some race fuel mixed with the pump gas. I've had my car since new 2001, I started modding it in the first six months I had it. I can tell you I have never even melted a plug. Look at times mph in sig. Some have said I'm wasting money on mixing race fuel or running race fuel on the street. I think I have saved money in the long run. I can't tell you how many threads like yours I've seen, running pump gas, 91 at that.

I'm not saying a stock short block should last forever, but detonation is a KILLER!

Good luck on your new build!

91 is as good as it gets for pump gas in Cali
