I am speaking the ZZX from TPIS. 239 239 .559 .559 112 lsa. Those are the specs they claim. I am looking for anyone that has degreed this cam or has had experience with it. I have seen very few people use it. I believe this is because it is a 375 dollar cam and you can get a comp cams cam for $250 of "similar specs." I am hesitant on a comp cams cam because they seem more universal. They sell the same cams for carbs, minirams, etc. I know I can get a custom cam from them but I have no idea the specs to get besides .050 duration and alot happens before the valve gets to .050.

I also know that I have seen some very very fast cars with it. Hoover the 10 second vette used it along the way as well as 11sec91z.

I think some dudes over on corvetteforum have used it. It doesn't seem like anything special, but the price knocks it out of the competition. If you are wanting specs, call cam motion, and have them fax you a spec sheet, fill it out, then they will fax you back their recommended cam. They sent me 235-239 .601-.604 lift.

You can also pick your own lobes from the comp catalog, and the tech dudes will help you if you have questions. Comp has the extreme energy lobes in 236 and 242, so something similar to the ZZX would be a 236-236 .585-.585, or a 242-242 .540 .540 with your choice of lsa, intake centerline, base circle, etc.

Mine was $240 plus $30 shipping.

 

Thanks for the reply.

I have searched and cannot find a phone number to Cam Motion. Do you have one?

Also, I believe this cam to be special. It made 11sec91z's car go 123 mph in the quarter NA. Do a search. That car is unreal.

Also, I think you fail to mention that there is alot more to cams then just picking the proper .050 duration. Intake closing is a major consideration. The comp cam lobes are just generic lobes. Now if someone can tell me what are good intake/exhaust opening/closings then I will get a comp cams custom.

Did I mention that the lobes on this cam are asymetrical? I have not seen any other cam companies use this technology.

 

I didn't know tpis used special lobes on that cam. I thought there was a guy selling a used ZZX on corvetteforum, you might want to search in the for sale section to see if it's still for sale.

Many cams out there have asymmetrical lobes, they just dont mention it. Pretty sure the comp xtreme line are all that way, and I know Crane is making some too.

 

Hey! That number didn't work!! Is that correct?

 

Sort of..

I just orderd the ZZX last night. It should be in the car in a couple of weeks. Comp to burn you a custom cam it is $500 a profile. So a dual pattern custom costs you a grand. TPIS has been there every step of this last combo. They are guestamating 530-550hp with the new cam. The cam I have now is a 236/242 .555/.576 on a 112. I run 116 plus at 3,600lbs with street tires. I am sure the car is capable of at least 119 with traction. It will wildly spin the tires at a 45 punch right now. I am going to run 1.6 rockers to gain full advantage of my head flow. I am shooting for 125mph N/A.

 

Lethal, I need a complete list of specs. And who did your tuning? How much was your ZZX? Could you please print your cam card for us?


Also, a Comp Cams Custom Cam is 258.75. I spoke with them last night. Where you got your pricing I will never know...

Madmax, you are correct on that asymetric lobes.

 

That price is for a custom cam with their lobe profiles. Ask them to grind you a cam with the ZZX specs and see what they say. It will be $500 for a single pattern. I don't have the cam yet, so no card. The cam cost me $385 shipped. I imported my sig from a nother sight. It's not all there but it is a pain to update. I have done the tuning as of late. I started with the TPIS level VI program and have tweaked the bin for Idle and Cruise. I havn't done any thing to WOT yet.

 

True, but you can pick any one of a number of lobe profiles they have available, including the xtreme profiles for the cost GoFaster listed. You can choose whatever you want from their available profiles for the intake and the exhaust. Been there, done that. They will make a custom cam with lobes in a totally different valve firing order than a normal SBC for $700. I have the written quote for that cam at home. They kept asking me what I wanted it for, and if I was sure about the valve arrangement

No way that a dual pattern custom cam would cost a grand, no way.

 

Look man I am just quoting what the guy at comp told me when I aske them to grind a ZZX specd cam for me. That was three days ago. Maby he was not as familiar with the comp cams policies as you guys are. He only worked there. I don't just make stuff up. I had originaly orderd a 242/242 .576/.576 with a 1.6 rocker. That just wasn't enough lift for me and a little more duration than I wanted. The next closest lift was .624 and that was to much and the closest duration was 236 not enough.

 

Well I think he was a little clueless then. I've ordered stuff from them when I was working at a parts store. I never ordered the $700 cam though, its part of an experiment, and $700 on an experiment isnt cash I wanna spend right now.

There are all sorts of cam grinders out there. Lunati, Cam Motion, Herbert all do custom stuff and have for many many years. I had a local guy here custom grind a stock core because there wasnt anything aftermarket available, for all of $75. Just gotta check around.

 

You are right about the experimenting. It costs too much. I just went with the ZZX from TPIS. That is the last experiment for me.

 

I hope it works.

 

:hail: ZZX..........might be pricey..but works awesome...pulls hard all the way up to 7000 rpm..think you will like it..

 

More to a cam than advertised specs (obviously)..... And if you think Myron is going to just publish all of the specs for his cams so others can copy them, you are sadly livin in a personal utopia......

 

11sec91Z. Do you have any issues with the 3.73 and the 28" tire? As in bog or any thing. What do you shift at and go through the lights at? I think you said you had a Vig 3,500 right. Would you go with more stall if you could?

 

11sec91Z. One more question. Are you running the 1.5rr on the cam? I will be running 1.6rr on mine to take full advantage of my heads.

 

i have 1.5 RRs on my car..i have no problems at all with bog..i have a ART CARR 3500 non lock up converter in my car. With the 28" drag radials on my car i go thru the traps at 5800-5900..which is a little low for my combo..think i will be switching to 4.11s this winter..i also wouldnt mind switching to a little more stall..around 4000-4200 perhaps..which i think would hopefully put me very close to a 10.99 or so on motor ..opened exhaust..11.20s closed up..also need long tube headers..but theres alot of things i need to go faster..but i want to stay in the very streetable range..so i cant complain

 

It looks like you still have a fair amount of hp and ET left on the table. I did some quick math and you have to be putting out 450rwhp to run 123+ with a 3550lb car. That is amazing with your current combo. But then again combo is what it is all about. If I could trap 125, I would be done with the car. Thanks for all the feed back and the off line rim back spacing.

 

No problem Lethal..Yea i do feel i still have alot of ET left in my car for the MPH it runs..And by the way if anyone told me my car was goin to almost 124Mph when i had the motor built i woulda laughed..My goal was 11.70s and then i was supposed to be done but now it is 10.99 on motor removing no weight and all option still on the car ..a/c p/s ..cruise.windows ect..next weekend ill be opening it back up and hoping for cool weather..so im keeping my fingers crossed..And the fact that your car runs 116 is very good..mid 11s when you hook..try opening it once..see what happens..If you have the ZZX and we have similar combos you will see a drastic difference like me..anyways goodluck

 

11sec91Z. I think the car would go about 119-120 with some traction. I can't give it any more than half throttle in first and when I hit second I spin horribly and go side ways. I let out hit third and run out the top end. I run out of rpm at about the 1,100ft mark. I shift into O/D or bounce off the rev limiter at 6,700rpm. I got the ZZX cam today and it is a little larger than specd. Plus the 1.6rr could potentialy add another 2* of duration and the lift is at .596/.598 now. I have the cam card but they sent me the wrong cam doctor spec sheet. I am not sure if I want to post the specs. Then again all I realy have is .050 and cam lift and lobe sep and open and close events. Not exactly giving away any secrets.

 

Duuuude! you have to tell me the specs! I have a zzx coming used so i have no card. how is it larger than spec?

 

All I got was What I posted earlier. Hit me up on the E-mail and I will give you the specs and the rest of the info. The sent me the wrong cam doctor and they won't send me the right one. Propriatary or what ever.

 

Gofaster. Here is the cam card specs as they pertain to my cam with a 1.5 rocker.

TPIS ZZX
adveritsed....290/290
.050..............240/240
lobe..............373/.373
valve.............558/.559
seperation....112+4*adv
int lobe.........108
BTDC............12.6
ABDC............48.1
BBDC............56.4
ATDC............4.3

I will be running a 1.6rr so the specs change to around 242/242 @ .050. And .596/.598. You can't really be sure how much the duration will change, but the average is around 2*. The lift is exact though.
I can't wait to run this SOB. I hope this helps.

 

You are my hero, man.

 

Int.
BeforeTopDeadCenter 12.6
AfterBottomDeadCenter 48.1
exh.
BeforeBottomDeadCenter 56.4
AfterTopDeadCenter 4.3

These are the timing events as the lifter starts to move off and back on to the cams base circle. Seat to Seat timing. Or when the valve opens and closes for each lobe, int exh. I hope that explains it alright.

 

Wait, 3.73 gears and 6700 rpm?!! That ought to go 130 mph easy even with TC slippage. Maybe you switched rear gears?

 

Wow, this thread really has me rethinking my cam. I have a cc306 - 230*/244* duration, .510"/.544" lift w/ 1.5 rockers on 112 LSA. It was a bonehead mistake on my part to get a dual pattern cam, AFR heads like my 195's make more power w/ a single pattern cam like the ZZX. Still, I want to see how it does w/ the cc306, and maybe put 1.5 rockers on the exhaust - I currently have all 1.6's right now. If I'm not happy after all that expirementing - I'll have no choice but to break down and buy a ZZX cam. It's hard to argue w/ 123+ MPH. :hail:

 

Gofaster. I thought the same thing. It would make sense with a 4.11 gear. I got back under the car and did the tire to drive shaft test and I have 3.73. The computer says that is an eight percent slip in the converter. I lock the converter now and at 6,100rpm the Auto-Xray says I am going 116. A little better but not much. Eight percent isn't bad for a 4,000 converter I would think. I made another post about this same situation. It seems to be the norm.

 

I know this post is old, but I just noticed something. I bought Lethal's car a few months ago and I was going through some of his old reciepts. TPIS had sent the zzx cam to the cam-dotor for analysis and I don't know if they messed up or what but wait till you read the valve timing specs.

Intake and Exhaust:
Lobe Cent. Sep =108.1 BTDC
valve Overlp =50.2 Crank Deg.

Intake specs:
Valve opening =26.3 BTDC
Lobe Center =104 ATDC
Dur .050 =262
Lift w/1.6 =.59269

Exhaust specs:
Valve opening =66.8 BTDC
Lobe Cent. =112 ATDC
Dur .050 =270.7
Lift w/1.5 =.57219

Give me your thoughts ASAP, maybe it's me but this cam is wayyy bigger than I could have ever imagined. Maybe I got the wrong sheet for a different cam, but I don't think so. I'll call TPIS to tell them about this. If the cam is this big, no wonder cars like 11sec91z are trapping 124mph with this cam.

 

Guys, ignore my last post, I'm assuming most of you did anyway, since no one replied. Anyway, I appear to be an idiot. I talked to TPIS and they said that sometimes the wrong sheet gets put in a cam box. The zzx specs are as they have always been which was stated in this post earlier.

 

How's the rebuild comming along?

Since my last post in this thread, I've learned to NOT second guess myself so much. I also got my car running and feel much better about my combination of parts.

 

It's coming great, thanks. I'm having the race shop build the entire shortblock for $150, which I think is a great deal. I want to make sure the best equipment is used to seal up the rings. The engine will be done by Fri, and I'd like to have it in the car by this weekend, but next week is fine. I still have to get some new titanium valve retainers to fit the new valve springs. It kind of ticksm me off that I already had some and they don't fit, oh well. I'll let you know what happens when I fire the engine up.

Later,
Joe

 

Here's my experience:

I ran a TPIS ZZ9 (not the ZZX). It is advertised as having 212 @.050. I took it to Dennis Wells' Racing and had it check on his computerized Cam Pro Plus. It checked at 208.2 @.050 The LSA is advertised at 112 and mine checked at 112.6. I have the entire printout saved on my HD as a *.doc file if anyone's interested.

So their quality control is very suspect.

CompCams: I used their catalog, selected both the intake and exhaust lobes I wanted from the listing near the back of the book for my current hydraulic roller. I ordered it on the LSA I wanted and specified no advance be ground in. Cost $250.00

Grind # CS-3192/3315HR114-0 224/230@.050 .605/.544 CRC ramps on 114.

They check each cam before it goes out the door and the Cam Card that you receive in the box is based on the computer's measurements: My Cam card shows the specs are right on the money.

I've been buying CompCams for well over 20 years and wouldn't use anything else in the !/4 mile BB engines I use to build. I'm sold on their quality control and their R&D department.

As I said, just my experience.

Hey, MadMax, you really started a revolution with your intake mods. I did mine and so did many others (guys from the CorvetteForum).

One guy sent me some pics today of how he had cut open his big tube runners and has removed all the dividing walls. I plan to do that too, as well as adding more volume to the plenum by cutting out the bottom, welding in some extensions to drop the plenum bottom down closer to the intake manifold.

Poor man's SuperRam.

I always give you the credit too. Well done guy.

Jake
