New Comp Cam ductile rollers

[Super6]

How many people are running these cams? I have my engine down now and i am undecided as to what i want roller or flat) i looked at these comp cam rollers at the comp website and have done numerous searches. I just want a reliable, low maintence ,and most of all a fast car comp cam game me their price at $345 for the cam alone. Went to summit and jegs punched in the part # and no go..Who has the best prices on these cams?............................................thanks Bob

I have the same question. I know some people are running them, but have not heard anything bad yet. I've sent emails out to vendors but only got one partial response.

This may be the answer to wiping lobes, so I might go this route (I don't have the $$$ for the billet setup).

roller

I found a good price on the cam for $254 but the lifters are like $350 so you will have about $800 in the cam by the time all is said and done...this is going to be my x-mas present so i guess i am going to do this. I did some searches and i think it was Nick Micale said the 206 roller was the one to go with...Maybe Nick could give us some info on these cams ..............thanks Bob

I have a 214 and haven't had any problems with it. I have the engine out and the top end off right now (head gasket) and the cam still looks perfect. I even put in used roller lifters with it and a used stock cam button.

Just today I ordered another one. A 212. This'll go in a spare engine I have sitting in my shop.

IMO there isn't a decision to make. Go roller.

I too am going with this type of cam. According to J. Merkel, this is the way to go for me. I opted for the 212/212 one and hoping to put the "cam" deal to rest. Maybe some more will chime in with more info on this type of cam. Inquiring minds want to know...... I think this is the answer to those who can't afford a billet (like me) but wants the same peace of mind that comes with it.

Chris, where did you order your stuff from, and did you get new springs, pushrods, timing set, etc with it or will you piece it together from different vendors?

"Insider" info

Comp makes a revolutionary spring called a "beehive". It has some really neat features.
1. Is a SIGNIFICANT reduction in valvetrain wt, due to the very small retainer and the fact it uses no inner spring or damper. My source tells me this is about like a conventional spring w/ titanium valves.
2. Will extend the rev range on a hyd roller a significant amt, due to the lower mass that the lifter has to support.
3. Not expensive compared to other setups.
4. Lifters can be run very close to zero preload.
I have a set. They check in at 170# on the seat @ 1.850" inst. hgt, and 370# at lift of .550. [218/212 CC billet hyd roller, w/ T&D 1.65 rockers]
A comparison: the 14 bolt Champ roller springs, [1.446"OD] are Crane Purple stripes rated at 140 and 380#. [I checked them at these values when the heads were new] After some 40 runs and a few dyno pulls, I found them at 100/310#.. not good for revving over 5700.. It's been suggested by some that killing springs is easy to do w/ hi RPM burnouts. They were right!!!... No more "John Force" burnouts..

In order to use these springs, you have to get the springs, pt# 26120, the titanium retainers, pt# 794, the 10* locks, pt # 611, and the locators, pt # 4697. The part numbers are completed by a -1, as CC does not package them in sets for a v-6.

We're going to see WTF happens! This sumbitch is either gonna rev, or come apart trying!!! No more puny old 133 mph passes, at the sick et of 11.99.

Some other changes too! Stay tuned for some wheelies and such!!!

I purchased the Comp Cam 69-400-8 hydraulic roller cam (218I/212E/112LSA; .511I/.504E@1.55, $239), Comp Cam 853-12 roller lifters ($295) and K-Motion K750 springs (130#@1.7"; 380#@1.15"; 1.050" bind; $102) from Dan at Wise Speed Shop (http://www.wisespeedshop.com). This was to replace a 224/224 hydraulic non-roller that wiped #3 exhaust. (Nothing but rollers for me from here on out.) Can't wait to get it installed and running again!

Thanks Buzz! I'm assuming you had to get new pushrods too?

 

[sumnerw]

Good question!

I haven't purchased the pushrods yet. I bought two adjustable rods covering different ranges (Trick Flow 9001 and 9002 from Summit; $11.39 each). Once installed, I'll be able to get an exact measurement and order a set of the proper length. I'm expecting that the pushrods I have right now won't be the right length.

[Bye 87GN]

Cool. Thanks for the adj. rod P/Ns.

I guess the roller lifters are 0 lash, so they should be pretty easy to measure? Hopefully they are all the same length (they SHOULD be)....

If your going to the expense of a hydralic roller, might as well consider some adjustable roller rockers, IMO. Then you can get the preload right all the time, and not play the pushrod lenght game as often.

That's what I'm doing.

I ordered the one yesterday from Jack Cotton. Jack does have the complete kit there but since I have some parts on hand I just ordered the cam. $300.

Beehive spring update

Just received a messed up order from CC. It seems as tho the pt # 4697 is NOT the part for the Champ head. The ID of the locator is .624, and should be .571. Comp Customer service says the 2nd week in Jan for the correct part # 4784...

 

[Bye 87GN]

Bastages!

I heard their customer service was not the greatest.

 

[NC87GN]

ATR billrt roller setup... IMO. There cams are proven. Costly yes but do it once and be done.

 

[Russ Merritt]

Chuck, any reason your going with more spring press than is recommended for that cam? CC recommends 26918 springs; 130 seat press, 317 open.

 

[Chuck Leeper]

more pressure?

Russ, the engineer at Comp recommended them. Said they would work well, as the mass of the valvetrain is significantly reduced, thus lowering the chance of problems w/ the lifters floating at higher RPM's.

Funny how the aftermarket guys call things revolutionary when they are just catching up to the technology used by the OEM's. GM has used beehive springs in the Gen III V8 since the engine came out in 97 and in the Series II 3800 since 95.

The benefits are there however. The steel spring retainer in the Gen III is 11 grams which is lighter than a lot of aftermarket Ti retainers.

Let me guess. GM buys the springs from Comp Cams??
