The engine was rebuilt over the course of most of last year.
I finally, (long story) got it all back from the engine builder September/2010 where it was rebuilt and bored .020 over.

It has 2 hillclimbs, and 3 SARRC races and 1 Time trial event on it.

In my opinion that's too short of an interval for rebuilds but this thing has been a thorn in my side for a while now.
