I have a 69730 predator with the std. compression height flat top from N.R in the motor. I am sure I'm 28thousands in the hole even with my +20 rod and I am running a 10 thousands head gasket. I'm also running the auto lite plug in it. I forget the number on the plug but its like 3910 maybe? anyway my piston kissed the plug a couple times when I was at ubly a couple weeks ago racing. I thought I had plenty of clearance but I guess not. what gives???[video]https://i.ytimg.com/vi/FwaU8X66DHo/mqdefault.jpg[/video]
that's a link to the racing I'm the very first race on the red doodle bug with the green helmet and green monster jacket. there's a few races of me in there. I hope this link works and you have to fast forward a little bit through the B.S at the start.
