Curious About a Arrington Engine CAM

[richierevs]

Anyone using the CC607 from Arrington Engines? If so, what CAM did you have before and why did you change? Here's the link to the CC607:

**Edit**

So no one, else, is confused, I changed the title of the thread. Uuuggghhh.

Curious About a CAM


Well, I'm 5' 8", 205lbs, late 40's, have dark hair (well some of it) and blue eyes. Enjoy nitrous lite dinners and smoky burn-outs.


But I'm taken Richie, sorry man.






Why don't you try a Scott or Erik, maybe you'll have better luck with them.

rofl.....I saw that coming from a mile away.

LMAO....I just fell off my chair....That deserves a beer.

Ok, now that I've put my 10.5 EE foot in my mouth. Can anyone seriously provide input?

[Hemi31]

Seriously you better make sure your heads can take that much lift......and not just the springs,retainer to seal clearance is just as important! Gen III heads won't take much more than .580 lift without modification to the valve guide boss for the seal or special retainers.

Thanks Eric. That's what I was looking for.

This is just me speaking... and in no way an attempt to rag on anyone or particualr product.

Arrington cams have great UPPER range RPMs but expectation on the Torque is a bit on the lower side than what I would like to be @. (for a 426)

This is not based on hear say\speculation ... but current REAL world testing & watching the results @ the track. A certain 426 losing 50 lbs of Torque from previous cam. ( and no not mine)

Currently will be another test on Friday @ the local track to see what happens with the cam advanced 6 degrees.

Your findings are consistent with the recommendations that Arrington is making as to advancing the cam timing. The CC607 they recommend a 2* advance and the CC645 they recommend 6*. I've also have confirmation on Eric's (Hemi31) info that the Arrington cams require head adjustments to handle the lift above .580.

FWIW, you can run just about any of the newer designed hydraulic cam with 4°-6° of advance with NO loss in top-end performance, assuming adequate clearances can be achieved.

The CC607 cams is as follows:

duration I E
@0.006" 278° 284°
@0.050" 227° 233°
@0.200" 151° 156°
max lift .353 .353
LSA 116°

I recommend running it 4°-6° advance, for an ICL of 110°-112°.

This is an assymetrical cam, with a stiff opening, for lots of area under the curve, and a nice, gentle closing, to minimize the "Infamous Hemi Tick", lol.

It's rather large for a stock 5.7/6.1 engine, and will not have adequate P-2-V clearance with the stock pistons. It'll make a 426 stroker motor purrrrrrr like a kitten @ 700 idle rpm, and still break the 600hp mark.

I have smaller versions available, for stock displacement engines. I am especially impressed with the performance of my 6.1L "stock replacement" cam.

With headers and a slight tweak of the tune, and stock 6.1L valvetrain, it's showing a hair over 500hp on an otherwise stock 6.1L crate engine. How's that for "stock replacement"?

For that matter, a hemi cam with ANY duration, ANY lift, and ANY LSA is just a phone call away. I can even custom spec a cam for each individual application, if so desired.

That's some "stock replacement" 6.1 cam! I don't remember reading about this break through, Is that stock head's, and a tweak to the stock tune. Do tell us more about it, And Maybe put up the dyno sheet too!

Id talk to Hemituner/AJ about this subject. He has tuned every arrington cam they have and on an engine dyno too. Im sure he has some pretty good insight on what they are capable of.

I've sent you a PM with contact info, I've got an immediate need so I'd like to get the scoop on this ASAP. I'm getting an adjustable cam timing kit so getting 4-6* won't be a problem and my Diamond forged pistons have valve reliefs.

**Edit**

FWIW, the Arrington website says that the max lift on the CC607 is .607 for both intake and exhaust. Why is your number lower (.353)? Also, the push rods offered by Arrington are designed for their CC6XX series of camshafts. From what I understand it's for durability and to adjust the valve lift. So their push rods must be either slightly shorter or longer than stock.

Yes, I've chatted with A.J. on this subject and he agrees that the CC607 is too much. However, if the CC607 can be ground to be less severe that may be an option.

Sifting through the various threads, I feel the need to say that I'm talking FLYWHEEL hp, not rear wheel.

I think Arrington's calls it a "CC581"...Here are the specs:

duration I E
@0.006" 266° 272°
@0.050" 215° 221°
@0.200" 138° 143°
max lift .338 .338
LSA 116°

The seat durations and valve lift are VERY close to the production 6.1L cam. idle quality and tuneability should follow suite.

It has a lot more area than the stock cam, and, as always with my cams, it is assymetrical with a fast opening/gentle closing.

Bone stock 6.1L straight from the box to the dyno, swap cams, bolt on a set of Kooks headers, tweak AFR and timing(even the stock cam benefits from this, lol).....and pull 505hp on Arrington's Superflow. The arrington guys were so impressed, that a certain Arrington cam that is known to be soft on the bottom might very well be phased out.

Damn near tied Comp's xfi273 hemi cam on the top, and trampled all over it mid-range and bottom end.........

Just goes to show that using the "right" cam is always better than a "bigger" cam.

Maybe Arrington's can display the dyno sheets? Not my department, lol.
