What main componant dictates an engines highest rpm...without self destructing

[1972ChevyGuy]

Hard to say... it's all gotta work together. For power over a certain rpm its the manifold. But if you have the manifold and rev it too high, it can float the valves, throw a rod, break a spring.. ect ect... But IMO, the most important thing if you want high revs is the crank

the weakest link

I'd say that the main factor is weather or not your engine and every other component in the drivetrain has been professionally balanced. Then of course valve springs, forged crank and rods, ARP studs......... All depends on what you put in to it.

My "opinion" is the valve train...all things being equal. And I assume you are talking about the mechanical limitations...other things may have an impact on the attainable RPM...

smart@#$ Randy ....gotta leave it to the ex-huffer guys...well what about Nitrous....say a fogger running 350hp spray....

Lets Say You Are Putting In A New Cam , Manifold , Heads Etc, How Do You Determine Where Your New Shift Points Would Be?

Assuming the parts above are matched properly, the type of cam, heads and manifold should give you a rpm power range....however the best way to tell is with a motor/chassis dyno....I assume you are replacing the lifters and pushrods and springs too?

You don't really shift at max RPM, you want to shift after you have run the motor through it's power curve in it's previous gear...you can probably tell where the curve is by the seat of your pants, but a dyno would be much better. hope that helps.

There is no simple answer to that question. Every part of the system plays a role. Some things will only perform to a certain point, like the ignition system, fuel system, valve train, intake, and exhaust. If you floor it in neutral (not recommended) The engine will only rev to a certain point and stay there. Wether or not it will self destruct depends on other factors, mainly in the bottom end. Strength and balance of the crank, rods, pistons, and block, and the performance of the oiling system will determine wether it will blow up or not.
