I tell you how to read posts because I interpret it how it was intended,
You're a tool... because you think u'r interpretation is the only correct one.

What does the # of cyl. have to do with anything?

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.

I know what you're talking about as well... too bad you don't seem to be able to interpret that eh

Listen, I'm telling you that I understood what he said because he is speaking my language. We are talking about a Small Block Ford engine, not a VR6 and not a 1.8T. NUmber of cylinders has to do with everything, a 4 cyl will rev higher than a V8 because it has to to make reasonable power. Most of todays 4 cylinders can rev up to 8000rpm without blowing up and can make power up there (7000-7500rpm) because they have the head and intake flow to do it. Our big clunky V8 just doesnt have the airflow capacity, not only that the block just cant handle those kinds of RPM's. Also, you can't really knife edge a 302 crank because the counterweights are huge. It's much easier to do on a 4 cylinder crank because the counterweights are smaller and much closer together.
Now let's go back to where this started:
Quote:
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.
Quote:
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
Believe it or not, balancing is not REQUIRED to rev high. We do it because we want our motors to last. You're trying to be a smart ass and explain why it is needed, but it isnt required. If your motor is capable of withstanding those kinds of RPMs and you want it to last, then you balance it. BUT, we're not arguing that he wants the motor to last. We all know its better if you balance, hell my motor is balanced but it never sees beyond 5700RPM.
The bottom line is that balancing is not required, but you are right that it should be done if you intend to keep your motor together. Anyways, I could go on forever but I'd rather not. I'll let Strokerace explain exactly what he meant, because I'm pretty sure we're on the same page.

I can't really say anything to that extent. I have not been in the car or know what he is running. Can a ford go that high? yes it can. Does he have the right stuff?? I don't know.
I can tell you this from things I have seen. There is a guy that goes to the track alot. He has a stang and using scrape yard motors. He jams a 300 shot to it and runs in the 11's on stock motors. He may get a day out of it sometimes more. What he revs at, I don't know. But he doesn't care as he gets the motors cheap from the scrape yard.
As for MR VR. Read,read and then learn to read some more. Your lack of knowledge is really irritating me. Knife edgeing and balancing a crank will never allow you to rev higher then what your head,valves,intake and fuel system will allow. Get you head out of the stupid import magize and take up some machining courses and you will understand.

How come Stang_Seller understood exactly what I ment? I guess its the difference from actually doing it and reading about it, or is it that import owners think they know it all because some stupid magizine artical says its the only way.
Hmm, the Vega only has a balanced crank. But it wasn't balanced with the rods. It does not have a knife edge on it either, but it revs to 7400 without any problems. You can fell that the rods and crank isn't balanced together. Its also has been running like that for over 2 yrs with out a problem.
Heres another useless fact for you. This one is actually something that you know as its a VW motor.
A 1.6 rabbit motor(the size could be wrong, just incase MR VR disagrees with it) custom intake with 4 webber downdrafts. Built head and the largest cam you can find for a VW ( had to remove material on head to get it to turn) Did not have a knife edged or balanced shaft in it and rev to 10,000. It ran is the formula ford class(now the name may have changed, this was 18 yrs ago and may have misunderstood the name). He also won almost every race he was in. He was winning so much, that someone broke into his shop and stole the head off the car.
So, until you have something usefull and have the ability to actually back up what you say. I don't think you should say anything at all.
I love how everyone is so uptight about my motor.
Stang seller yourright a stock motor and stock heads should not be able to rev that high. A miss shift on a stock 02 to 8gs will stay together but for how long at how many times.?
My 02 was not stock. Just as my 351 i have is not stock.
But to give you an idea as what was there the Motor was a balanced and blueprinted motor. It had a Stock block. The bottem end was built as a drag boat bottom end.
I have told people over and over that the builder was into building race car motors and hydo as well as drag motors.
What failed was roller setup and it spun a roller lifter that jamed the cam and snaped chain and well then bad things happen fast.
Zexhuffer helped push the car off the road that night.
After that car got a mostly stock 02 to get me by then i went 351's
As for E7 heads. This might help stang seller out. I ported the shit out of them.
You know the emisions hump in the Exhaust of E7s well i grined that off then taped the hole and put a cast stich in there. Now when you open them up and trust me i opended them up alot, I also did all around the vaulve stem and smothened it out as well asl doing sides botom and roof. I didn;t bother to rase the bottom and go that far. But i also did everything i can do to chamber then the builder put time in to them to do more tricks.
Note i would not sugest doing this much work to a set of heads but when money is tight and you have free time then hey it dont hurt to play. Nowthe intake was a Vic jr, Not a super Vic. they were not even made then. I got the Vic jr used and it had been ported out and worked over. I had to open heads up alot to get them portmatched to this intake so ended up doing more work to the heads on the intake side as well.
Rest is easy i have told people time and time again i had 540 lift roller cam and not the X303 but its alot like it.
Stang seller if u want more info that easy to do.
If you want to know whats in my little 351 i can give you everything and you can go off and ponder that motor too.
There are 2 ways of doing things, Powerfull motor light car and you dont need to rev as high. Or heavy car with motor that dont make as much power but revs higher.
I took hard way. And 02 was a stone till it hit 3000rpm then it came to life
Dont know were he has been hidding. Odds are he has been working his @ss off.
I need to get some good tires on my car.
Ones i have are almost on wear bars but still goes ok in the snow.
I guess it time to do a vid sliding the car around.

Now let's go back to where this started:
Honestly, I totally agree with everything you've said so far... so maybe we're just not on the same page here... I understand that the V8 u'r talking about doesn't have the flow to REV that high. And I never disputed that.

Well I guess it's not a matter of me being a smart ass, but in my mind something that will make a motor last for doing what I ask of it (ie. REV) means to me it is required.
Quote:

To me that is a requirement

Again I agree... I guess we were the ones that were on the wrong page.. lol...

I honestly would like to know how exactly you know that this Rabbit motor didn't have balanced internals.
