I doubt it's possible but...

A 300 with glasspack exhaust sounds quite close at idle, and packs even more cubes per cylinder. So, you still need to figure out how to make it breathe like a Cleveland :shock:

I think nobody has ever experimented with varying mufflers on a 1-5-3 / 6-2-4 dual setup before, and probably with good reason.
 
no, a 200 cube i6 will NEVER sound lilke a 351 cleveland.

you can prolly get it to idle similarly, but not when you jump on it.
 
Abnd the Ford 460 is a crossplane correct? not that im putting one in my mustang, i wouldnt abandon my six

So which cam would give me that nicey lumity-lump sound?

One you wouldn't want to live with in anything remotely like a daily driver. The thing would be a pain in the neck to drive and it would have terrible fuel economy. Worse than that it wouldn't even be more powerful unless you spent a lot more on the engine than you probably have any intention of spending.
 
I'm not sure you you can get that v-8 sound, but you can get an equally attractive and more appropriate hi-po six sound. I'd start with a seriously ported head or the new aluminum head, as high compression as you can get away with (probably around 9:1 on a factory head, maybe 10:1 on the new head, anybody??) a lumpy cam (read the tech section at classic inlines - ironically, the lumpier cams actually produce better low end power, if I'm reading correctly) and a dual out header through a pair of 2-1/4" or 2-1/2" glasspacks or flowmasters. Short pipes exiting ahead of the rear wheels might help, too. It won't sound like a Boss 302, but it will sound seriously bad ass. In fact, it will be seriously bad ass and will only set you back, oh, 5 or 6 grand :shock: !!!

Actually, if you started with the dual out headers and a nice dual exhaust you'd be well on your way. When I had just installed my headers and was driving to the muffler shop it sounded very cool. It wasn't much faster, but it sounded good.
 
a lumpy cam (read the tech section at classic inlines - ironically, the lumpier cams actually produce better low end power

If "better" you mean "strangling on the excess exhaust gas in the chamber and straining to produce enough power from the low cylinder pressure to prevent stalling", that would be right.

That rilly kewwlll sound is your engine telling you it's running very badly, which is exactly how it will perform at low speed.
 
if you modify it and leave it open header it sounds very similar to that

perhaps to the owner, and his closest friends.
Everyone else on the planet knows it's a 6 with a loud muffler.

i would beg to differ before my car got wrecked i would challenge people to guess what motor i had under the hood just from the sound of the exhaust and not a single person believed it was an I6 after they had guessed wrong until i popped the hood and proved them wrong
 
I've always felt there should be a direct relationship between how loud a car is and how powerful it is. There are plenty of cars in my neighborhood with coffee can mufflers and otherwise stock engines. A loud, boomy Honda Accord is definitely NOT cool, or "kewwll" as our disgruntled friend would say. Certainly having a loud but slow car might be amusing for a day or two, but it gets old quickly.
The reason that Boss 302 sounds cool is not because it's loud, but because you can tell from the quality of the sound that it is powerful. Notice I said quality and not quantity.

Now, I'm no engineer, but I have been wrenching on sports and race cars for over twenty-four years. Perhaps Kitabel knows more about this than I do, but from what I know about cams, a lumpy idle doesn't necissarily mean your car is "strangling on the excess exhaust gas in the chamber and straining to produce enough power from the low cylinder pressure to prevent stalling" Allow me to quote from the Classic Inlines web page (it was convenient)

"The lobe center controls where the power curve is applied. This cam with a 112* lobe center will come on around 3500 RPM (not to be confused with the power curve - which happens to be the same RPM). Changing the lobe center to 110* will lower the point where the cam starts working (kicks in) to about 3000 RPM. And changing it to 108* will lower it to approximately 2500 RPM.

Therefore, this cam with a 112* lobe center will perform best from 3500 RPM to 7000 RPM. Most of our sixes will never see 7000 RPM, so in my opinion it is too much. The same cam with a 110* lobe center, will perform best from 3000 RPM to 6500 RPM, which is where most prefer. The cam with a 108* lobe center, will perform best from 2500 RPM to 6000 RPM, which is great for a mild street racer.

But keep in mind, a cam with a 112 lobe center will idle better than one with a 110* lobe center. And a 110* better than one with 108* lobe centers. A 112* will give a smooth idle, 110* will be a bit lopey, and 108* will be choppy. The 108* cam is fine with a manual tranny, but an automatic may require a matched stall converter (2400-2500 RPM stall) for ultimate performance."

So yes, lumpy is decidedly a PITA for a daily driver, especially with an automatic. However, I stand by my statement that if what you want is a mean sounding six (notice I didn't say loud) that actually has some muscle to back up the sound, then a lumpy cam ( and high compression) might be a good choice for you.
