My car lasted for a while with a 7K rev limiter on stock rod bolts, but at 33K miles just recently threw a rod out of the block. When you're pushing it that hard, you never know when it might go.

How much timing were you running? It seems like most people around here run 28 degrees. This seems odd to me, since thats the factory timing map on my '99 FRC. I'd think with higher CR, obviously much higher cylinder pressure (more power) and tighter quench you could run less timing without loosing (or maybe picking up some) power. Also, it seems like some people run a flat timing curve. In my experience, a motor likes the least timing at its torque peak (highest cyl pressure), and it falls off as it revs higher.
