not the best video or sound quality but I bet my neighbors loved it lol. trying to decide if I like the way the cam sounds im thinkinging about changing it. I know its either putting one dominator on it or going with a tunnel ram

---

You have a 700hp 484" Hemi and you're wanting to swap cams because of the sound???? You're on crack! It sounds like it's supposed to! If you want a Joe Dirte "lopey" idle, put some small tube headers on it along with 2" exhaust and some really restrictive mufflers....


Contrary to popular belief, the camshaft is not what makes a "lopey" idle....it's the exhaust system....Have you ever seen/heard a car with zoomies have a "lopey" idle??? NOPE....and you never will no matter what camshaft is in it....

---

Really,

so how do you explain that when you change cams from the stock one, and it idles fine, and then put a bigger one it, it lopes?? Everything remained the same except the cam????

Have to say, never heard this before.

More overlap in the new camshaft is just showing you how ineffecient your exhaust system is because now it's running on exhaust...

It's called reversion because the exhaust doesn't flow good enough...put zoomies on it and it won't have a "lopey" idle...

Another way to make one sound Joe Dirte "lopey" is to fatten the idle circuit a whole bunch and/or pull initial timing out of it...

The motor in the video sounds PERFECT and is what people should be aiming for....

Have you ever seen a sling shot or super comp dragster idle " lopey"??

If that is the case, someone should tell those morons in PS and the AH cars they don't know that they are doing.

I've heard plenty of those cars idle in person and I never said they don't know what they were doing...They sound more like the motor in the posted video than they do the typical over cam'd/under exhausted small block Chevy at the local cruise night that has what's considered a "lopey" idle...and I'll bet you $10,000 that a Pro Stock and SS/AH car's idle will smooth out if you put zoomies on it....

There's a HUGE difference between a slightly erratic idle and what the average car guy considers "lopey"...The reason that a Pro Stock car and SS/AH Hemi have an erratic idle still boils down to exhaust flow....at idle it's just not moving fast enough in the header to get out so the motor sucks exhaust back in during overlap...You can put ANY cam you want into any motor with zoomies and it will not idle "lopey"... and what will actually happen is that with short zoomies the motor will suck in fresh air through the zoomies and run on that air as if it has a vacuum leak so you'll have to shut the throttle blades all the way... Been there, done that...

I'm not buying your exhaust theory.... even with
open headers my cam sounds the same... and my headers
are made to the engine specs.... over lap causes
the lope

---

It's not theory, it's fact....I've done it...

Put your motor on a test stand with zoomies or block hugger, shorty headers and run it and you'll see for yourself...Anything with a "lopey" idle will smooth right out with zoomies, but you need to be prepared to close the throttle blades all the way and it will still idle at 1,200-1,500RPM+ depending on how much overlap the cam has because it will be running on the fresh oxygen that it's pulling in through the headers.......

Overlap does cause the "lope" but because it's sucking exhaust in, correct?? So, the more restrictive or longer the exhaust system is, the more of a chance the motor has at sucking in exhaust during overlap.......your headers hold enough exhaust in them that the motor is trying to idle on it because airflow isn't fast enough to push exhaust out (at low RPM)...once the air speed picks up, the motor smooths out...

If every cylinder has the exact same lobe profile, why does the motor idle erratic if it's not sucking in exhaust??

Have you ever heard a car with zoomie headers idle with "lope"?? The answer is "no" and you never will......

Over lap is drawing in part of the next fuel charge...
I put almost 2 identical cams with just different
LSA and the wide cam idled smooth with no lope at
all the 107 has the lope .. same engine with everything
the same except the cam LSA.... your entitled to
your opinion and I have mine... so I'll just let it
go at that

I need to change classes or get a lot faster

lol you don't have to change classes because of this car the chassis is killer the motor is not im willing to say its a 10.50 car at BEST ive been kicking around the idea of selling my hemi and doing a gen 3 one with a turbo or two hanging off it just to try and get the car lighter.

I'm really not trying to sound like a butthead, but you're wrong...it's "lopey" with more overlap because it's pulling in more exhaust into the intake manifold...I'm sure you've heard of "reversion"? Reversion has nothing to do with "pulling in part of the next fuel charge"...I've done it...it's not my opinion...it's fact...next time your motor is out, run it on a test stand with zoomies or short, block hugger headers and you'll see I'm right...

Have you ever seen a motor that's got way too much overlap and the intake manifold and inside of the carb is black? That's soot from the exhaust...

You're the one working off theories and opinion, not me...I've actually done what I've described and it's 100% true...just try it...

You still haven't answered my question, so I'll ask it for a third time...Have you ever heard a sling shot dragster with zoomies idle "lopey"?? No, you have not...the only way a motor with zoomies will idle "lopey" is if the timing is really low and it's really fat...

I'm so confident in what I'm saying that I'll put my money where my mouth is...I'll put a motor on my run-in stand... Run it with long tube headers to show you the "lopey" idle and then install some block hugger headers to prove it smooths out and it will idle at least 300-400rpm higher with the throttle blades all the way shut...just put up 2K to make it worth my time and drive on down to Oologah, Oklahoma and collect your money...

BTW, I'll cover all bets if anyone wants to get in on the action??

I dont know what it takes with you but I put 2 cams
in like I said... one wide LSA and no lope and one
with a tight LSA and it loped ALL the rest of the
engine same... but I'll go back and tell the cam lab
guys they have been wrong all these years... as well
as the cam companies
Oh..... I NEVER have black in the carb....
so lets just say you have your idea and I have mine
and let the guys think what they want... OK

I don't know what it takes with you, but I've got $2,000 cash that says I'm right and your wrong....I'll PROVE it to you in person.....Come take my money....... If 2K isn't enough for you to fly or drive to Oklahoma, name the amount......3K?? 4K?? 5K?? Name it....... You're trying to nicely call me a liar, and I'm nicely trying to pay you to teach me a lesson........

I'm not saying that what you've done isn't happening........I believe you......but it's because of reversion.....the motor is idling on exhaust because more overlap is allowing more exhaust into the intake tract.......Do your test with zoomie headers or block hugger headers and see what happens........

Cam lab guys aren't working with zoomies.......Tell them to try zoomies and see what happens......

I never said your motor had black soot in the intake or carb....I've seen that on customer's cars and figured you may have seen that before?? Guess not...

I don't have an "idea" or "theory" like you've already said.......I have FACT.........and I'll prove that you're the one with "ideas" and "theories".....and I'll even pay you to prove me wrong.......

SLOW67..........You're not reading everything I'm saying......YES.....the camshaft will change the idle BUT it's because of reversion, not "pulling in part of the next fuel charge"

Blusmbl.....I agree......I never said that a camshaft doesn't effect the sound, or "lopeyness" of an idle.......All I'm saying is that you can take ANY motor with zoomies, and it won't have a "lopey" idle, unless timing is way retarded and it's very rich.....so, if I can prove to you guys that that's actually true, then it's the EXHAUST SYSTEM (including headers) and NOT so much the camshaft causing the "lopey" idle...AND THAT'S A FACT THAT I'LL WAGER ON

The OP's motor sounds perfect......and to change the camshaft just to TRY to get a different sound is crazy IMHO......
