Question for any engine geniuses on the forum....

Is there any way other than trial and error to estimate the SAFE redline of a worked engine?

Example: Stock SR redline is 7400 or so, but if you do head work and valvetrain work, clearly, the car could safely rev hgiher.

So, is it siimply a matter of someone doing the mods, and then trying to rev the engine higher (trial and error), or is there some systematic way to determine the new SAFE limit?

Just interested.....
