A little nervous!

I built stuff, broke it in making sure nothing was leaking, etc. Sprayed the street down and did normal burnouts and launches. Break in time/miles... What's that???? Straight to the track/testing or street races.

If it was on a dyno, do they baby it or run it hard? Think about that for a minute. Machine work is much more accurate than 40 years ago and the 500 mile BS thing.

If it steer and stops fine, run it hard and let the sniper self tune.
