See all this dumb hillbilly has to do is admit that the tach may have been off but this clown refuses to admit that he could have ever been wrong.

Now the last 2l 16v VW engine I had, was built and balanced, and could rev. BUT, it was balanced, knife edged, and I spent a small fortune on that crank. Stock cranks, don't rev that high unless, they are rolling down the highway after being shot out the bottom.

Ok, you just made yourself look totally bad and stupid with that comment. Your crank has nothing to do with how high the engine rev's. Balancing has nothing to do with it either. The rods and cranks are balanced to stop vibrations at high rpms. The knife edge is to help it cut through the oil without drag and to stop the oil from foaming at higher rpm's. Come on, a newbie even knows that one. Your valves, head, cam, intake are all part of how high you can rev the motor. The rest is just there for the ride and reinforced to take the pressures created from the combustion forces.

LOL! The only person I've ever head that say balancing isn't needed to rev high...
It never ceases to amaze....
Vibrations get stronger the higher you REV a motor, and factory balancing is only done for as high as factory specs allow... if you plan on REVing a motor past factory specs you'll need (along with top end work) a properly balanced bottom end

You guys are all mistaking what he is saying. He isnt advising against having it all balanced blah blah blah. All he is saying is that ITS NOT NECESSARY for the engine to be balanced and the crank knife edged for the engine to reach those kind of RPM's. Without balancing, the engine will likely self destruct much quicker. Knife edging also helps maintain the engine and frees up some power due to less cavitation and less drag, respectively.
People need to slow down and properly read the posts before getting all hot and heated, this is why the internet is full of stupid arguements when both sides are saying the exact same things. Reading skills are more important than typing skills, I say. Sorry if I seem a bit sour, I just woke up after 3 hours of sleep.

That's like saying head work isn't NECESSARY to REV that high... Because it's not... Take out the REV limiter, and u can rev as high as you want... just watch u'r motor go boom when you do.
When a motor is going to be pushed past factory limits there are certain things you should do to make sure u'r motor doesn't end up as a very expensive paper weight.

And you need to stop telling people how to read posts... Just because you read a post one way doesn't mean you are correct, nor does it mean you read it in the way the original poster ment it.

Lets take into consideration who wrote the post, Strokerace.
Factory parts are not that refined in a stock 302. Yes take out the rev limiter and it will rev that high, then grenade.
I would not rev a stock 302 past 5200-5600. Anyone who says theyre revving to 8500 on stock parts is lying and wasting their time.
Who cares about a 16v motor, were talking about Randys 302. Its far too easy to change the subject and forget what were after here, the truth.

I tell you how to read posts because I interpret it how it was intended, you read it like all the other 4 banger guys. We're not here to reinvent the wheel, just to prove that SirChirpAlot is a retard who is full of shit. We're not talking about all the other aspects of building a motor that will make it capable of revving that high. We're talking about a stock 302 Mustang engine that CANNOT under any circumstance rev beyond 7000RPM without going boom, balanced or not. 2Tone has the right idea, he knows just what I'm talking about. If you dont know what's being cooked up, stay the **** out the kitchen.
