Ok, ok -- I'll shift! (LOL) Thanks to all who took the time to respond. I should have realized that I'd hit the top end of my power band before I hit redline....

So now that you all got me thinkin' (UH - OH!!!!!), what is the definition of REDLINE? I assumed it was the point where your engine would come apart (at least the point where damage would occur). I also know that there would be a difference between just touching a high RPM and SUSTAINING a high RPM.

When I first posted the question, I think I knew what I was trying to ask, but I didn't do a very good job asking.

When buying parts, manufacturers typically give limit recommendations (but when they do, do they mean peak momentary RPM or do they mean sustained RPM?). Staying within their parameters keeps rods from throwing, valve springs from weakening, etc. I also know there are general rules of thumb on cast vs. forged parts. But what about the small stuff like rod bolts and the like? Shot peening rods with strengthen them, but to what degree over the unmodified part?

I guess the best question is, if I do a reasonable job with part selection, pick forged parts and high strength fasteners, use a good machine shop, and torque EVERYTHING, do I have to worry about making my new engine a coffee table or a boat anchor?

In the mean time, I'll take the advice to get more reading material on the subject. I do like posting questions here, though, because more times than not, you guys fill in the gaps that the books and articles leave.

Keep up the good fight......
