Have you guys heard about Coates spherical rotary valve cylinder heads? I read an article on how they applied them to a 5.0 and it raised the redline to 14,000 rpms. And gave it over 550 horse power but they didnt say what they had to mod on the motor if anything. I could'nt pull hardly any more info then what I got from their site so if anyone has anything let me know cause I am curious.

Its only a demonstration of the capabilities of the heads. No one spun a 5L V8 14,000 rpm. I don't think you could physically spin a rotating assembly the size of our motors that fast, let alone on parts out of the jegs catalog.

uuuhhhh... These heads are not out of the jegs catalog and as far as I know they arent even available to the public as of right now, and if they were they would carry an estimated price tag of fifteen thousand dollars. check out the website at www.coatesengine.com... It must be nice to express your thoughts about something which you know nothing about.

Hey stupid... Read my post through before you jump my ****.
you said - I read an article on how they applied them to a 5.0 and it raised the redline to 14,000 rpms. And gave it over 550 horse power but they didnt say what they had to mod on the motor if anything. I'm saying, you CAN NOT modify a 5L V8 in any way to make it withstand 14,000 rpm... ESPECIALLY on your average hot rod parts, that you would order out of Jegs, or similiar catalog. So, learn to read. Learn basic comprehension skills.
P.S. Your the idiot that thinks some guys put some magical F1 heads on a 5.0 and revved that **** up to 14,000 and made 550 horsepower... Do you believe in the tooth fairy, too?

Hey before you get your panties all in a bundle why dont you check out coatesengines.com and read up a little if you can and they are not some magical cylinder heads, they replace the whole existing poppit style valve system completely and eliminate hundreds of moving parts, and the spherical rotary valve cylinder heads do not require oil, and also move 150% more cfm than conventional poppit heads.... srvc heads (331cfm) poppit heads(125cfm). do the math and think before you speak. you made it sound like the heads were from jegs in your previous post.. Little hint specifics never hurt anyone. The little tooth fairy comment was cute, what are you fourteen ...? come on, unless you have something usefull to say noob keep your mouth shut and let the grown ups do the talking. Now that being said , if you would like to learn something about innovative technology in internal combustion engines check out that web site and read up on it .... p.s. you can thank me later.

I'm telling you right now, you can put whatever heads on a 5.0 you like and it isn't going to rev anywhere near 14,000 rpm. The rotating assemby (do you know what that is?) will not spin that fast. PERIOD.
I never made it sound like the heads were from Jegs, but you thinking the motor may not even need to be modded is retarded. Building a whole short block out of the best production parts you can find will not bring you anywhere near capabilities of 14K rpm.
Heres what you should do. Run your gay little self down to the local community college, and sign up for the most basic physics class offered. Maybe then you would understand whats going on, before you turn all hypocritical on me and twist yourself up in a knot.

I appologize if I'm being brash. I thought my original post was pretty easy to read, no intent to be arrogant or anything. Anyone else have anything to add?

I would like to see a link directly to the article refrenced above.
I also would have to agree I there is no practical way to spin any V8 small block 14k RPMs, theoretical redlines are worthless. It doesn't matter that the head will work to those RPMs because the motor would grenade its self long before 14k RPMs. On a race only NA V8 you might see 8500-9k RPMs but to increase that another 5k RPMs is a lot to ask. These are motors using lightweight cranks, aluminum rods, lightweight pistons, and lightweight valvetrains I can promise you that you wouldn't want aluminum rods on the street.
Perhaps, he was simply stating what he read and thought it was crazy and asked anyone if they knew about it because he couldn't find any further information on them.
Actually, that is exactly what he asked.

Hey quiksvt I know you are challenged so I put a little link for you, call me a liar and your calling them liars http://coatesengine.com/engine_of_the_future.html There you go lil feller...... check it if, you cant figure it out, give me a call and I will read it you. And do your self a favor stop prettending that you now $hit cause you dont. Wah wah wah the rotating assembly.. the rotating assembly.... If a rotating assembly is balanced and proportional whether it be a Pratt/Whitney f220 turbo fan jettison motor for an F-15 or a a lawn mower they all have rotating assemblies and there are always ways around obstacles. Let me guess... you bag groceries for living? I know your fresh out of high school and you know everything, but if you calm yourself and stop being so high strung your balls are never gonna drop. I have a college degree thank you for asking Iam glad you were concerned, and I happen to be certified to work on some of the most advanced avionics systems for fighter aircraft in the world, and fly as well so check your self there smart guy. I dont know what makes me more angry; The fact that I am getting personal, the fact that I am coming down to your level, or that I am wasting my time arguing with an obviously challenged individual.
For you innocent by standards out there I appologize with my deepest sympathies for the immaturity that you have wittnessed within this post but some people just try to get too personal and dont care about expanding their horrizons, but if you guys have any question pertaining to the heads and the motor click on the link because its pretty fascinating.
I've been drinking so I didn't feel like reading the whole speal in the link, but what I did skim over, it seems like it is crazy, new, innovative stuff. It also kinda seemed like it was more than just heads. A whole engine perhaps?

yeah they took a 302 block but I dont know what they did to it thats why I posted the whole thing in the first place, wondering if anyone else had any more info on the whole system I heard rumors from some friends that work at a performance shop that it was a stock motor, and they took out the whole lifter assembly and got a custom timing chain, but you know how rumors are. I just wanted some facts. I appreciate the reply sorry again for all the bull$hit.

You call me immature? Ha. Your such an educated, certified, wrenching, flying, perfect individual yet your posts are full of name calling, degradation, little fact, and lots of fantasy horsecrap.
In your previous post, you expressed that you really, truly believed it may be possible that they bolted these heads on a 5.0 and revved it up to 14,000 rpm. Now, after I simply stated its not possible, even with all the mainstream fancy internals sold to the public (i.e. Jegs or equivalent comment) to spin a 5L V8 motor near such a speed, you pop off about a balanced and proportional rotating assembly. Basically, what your telling me is that, hell, if its all balanced it can be spun to an infinite rpm, right? Haha. I guess there is a reason you supposedly work on avionics, because with your lack of knowledge regarding a such a basic, simple matter it would be certain suicide for you to be let anywhere near a powerplant.
I don't understand why you went so ballistic on me? Show me where in my first post I provoked any sort of angry behavior from you. Please, stop being a hypocrite by telling me to calm down, etc when I am the one sitting here laughing at your ignorance and obviously out of control temper.
You asked a question. You got an answer. You got mad? WTF? Theres a saying, "don't ask questions you already know the answer to". Seeing as you are obviously far more knowledgeable than myself or anyone else, why did you ask such a question? Couldn't you have saved yourself the time, and periods of high blood pressure pounding away on your keyboard like an idiot?
What I do for a living is none of your concern, but I can assure you I don't bag groceries. My balls are also none of your concern. Learn to spell and punctuate. Have a nice day.

I am not going to waist any more effort with you are obviously mechanically challenged. grow up and read the article cause obviously you havent, your the only one that doesnt get it.
