Went to Great Lakes Dragway for Street Tire Tuesday.
First run: 60ft= 2.177
1/4mi = 13.20 @ 111.31mph
2nd run: 60ft= 2.124
1/4mi= 13.07 @ 111.69mph
3rd run: 60ft= 2.068
1/4mi= 13.06 @ 111.01mph
4th run: Motor go BOOM!

I had a fantastic launch and the car was pulling hard. Just before the traps I think I over revved the engine trying to break into the 12 second realm. I heard this sickening pop sound and then the car shuddered. I cruised into the shut down area and noticed the car had a miss and there was a bad tink- tink- tink sound.
I instantly pulled it over on the return road and shut it off.
I didn't vent the block but there was a loud enough clanking sound to know something definitely was broken.
I think I either dropped a valve or broke a connecting rod. I'll find out when I get the motor pulled apart.
Bummer! It's the beginning of summer and my toy is broken.
I was contemplating going stroker. I guess I might be doing that sooner than I thought.
