Bottom End Rev...

How many people are spinning their stock bottom ends (Rod bolts or not) to 6800 because they're using a MS4 or T Rex sized cam?

I want hit my goal of trapping 120mph on stock heads without any real weight reduction and driveline mods. The only way i'm gonna do that is to rev the engine passed 6500rpms. Just wondering how people are fairing with that.

My rev limiter is set at 7200... Shift light is at 6800. Stock '02 rod bolts.

But, I really want a new short block...

I had my limiter at 6800 for a few years, but recently upped it to 7000 because the HP curve flattens but dosnt drop till after 7K.
