We decided to go ahead and disclose all of our camshafts. Where most shops have 5-8 cams to choose from, we have 11 cams to choose from for each displacement. 440 cam specs are still being profiled as we speak.

These late model HEMI grinds are all manufactured from brand new, steel billet stock. These are not reground OEM cores.

These HEMI profiles are also machined under strict manufacturer's guidelines and profiled on the same CNC cam grinders that NASCAR and NHRA professionals have their pieces ground. They are not coming from a mass production cam grinder in Michigan.

Every billet camshaft sold by PPP is manufactured using the tightest SAE standards and are verified for their configurations. So far, no one else goes through this much effort to get you the best possible components for your project.

All the Power Ported Performance Pro series camshafts are inverted flank roller camshafts. Most others are asymmetrical but not as radical as the Pro series. These IR camshafts will require the use of the PPP heads and/or valvetrain kits or they will become unstable at higher RPM. There has been a lot or R&D with these Pro top end packages so to mismatch these profiles with cheap, imported hardware will not allow your engine to produce the maximum power possible.

veyr nice....when can we do the swap? ;)

Have you ever put your stage 4 pro-series 6.1 cam in anything? I would love to see how that does.

Not yet. We just finished that profile to go in a forged 6.1 shortblock with 11.1 compression and our new Stage 3 6.1 Heads that utilize a dual valve-spring and re-engineered valve-train designed to handle 8,000rpm, .650 lift, and 65psi.

Really, its about time we see one of these builds, no reason it should not be one of (the??) most powerful 426's out there....now, who's going to step up and build a nasty solid roller, cam only set up so we can see how much power can truly be wrung out of the stock 6.1 heads?

Do you have an guidelines for supporting mods, rpm ranges, or horsepower levels that would help in picking a cam?

i mean is a level 3 NA cam ok for a stock jeep with only a tune?

btw, thanks for releasing the cam specs... it is really interesting to see the numbers and to compare them!

LOL that would be insane Mike. I'll get one ground if you can make it idle:D

Sick, please get some videos of that beast.

Comp is looking into a solid lifter for us to go with a nice solid-roller camshaft. Johan will have his hands full with some of the stuff I am sending him. lol.

Hey Andy,

What is stage 4 cam shafts? Is 1 road, 2 track, and 3 race?

Also like you said pro series needs your heads as well correct?

What would you suggest someone who plans a FI setup in the future but wants a cam for now? I am really thinking about a track warrior for now but the 4 stages confused me.

What makes your valvetrain kits different from the Comps? Nothing I see there, other then the Stage 4s, should be out of the range of the standard Comp 26918 springs and 761 retainers. They're good for .600 lift.

Good for .600 lift for how long? What are the open-close seat pressures? What is the install height? We are running these cams currently with the PSI 1511 or the Manley 221428 spring with good success, but I do not recomend it. Springs are going to break, thats a given, the problem with a bee-hive is that when it does break, it will drop the valve into the motor and destroy it. The Dual-spring we are running in our new valvetrain does not run into coil-bind until .685 lift making it more appealing for these .600 lift camshafts. We will also have a new line-up of camshafts in the .625-.650 lift range as well for these extreme valve-train cylinder heads.

I actually eliminated the names of road, track, and race. The 6.1 Track Warrior is now the stage 2 NA camshaft.

How long? I'd assume as long as needed. Pressures are 130/318 closed/open. Installed height is 1.80" i believe, open height 1.20", coil bind at 1.140". Spring rate is 313lbs/in.

All beehives have a failure rate that the manufacturers consider acceptable, maybe you should contact comp and ask them what theres is. Springs fail especially when pushed to the limits. 318 pounds open is pretty soft. The PSI 1511 we use is about 350 pounds open and I still prefer the PAC Racing for the pro-series with its 450 pounds.

So are these new stage 3 heads matched with your new grind of cams going to be able to get a 6.1 jeep mid to high 11s N/A. I know Keoni got 11.93 with your stage 2 stuff. What are you looking for/expecting with your stage 3 line?

Right now only 1 jeep has run an 11 with heads/cam. I am shooting for consistent 11's with the new stage 3 heads/cams.

^^^^^^ A consistent 11's 6.1 jeep w/ H/C would be awesome...im sure your efforts would be rewarded greatly if you can accomplish this. Ill be coming your direction if I can hit 11's all day with H/C haha

where is the roller rockers? Dosent arrington have a prototype roller rocker set up. Are you guys going to be dealing with this too?

Thanks

does the NA cam stage 4 work with the stock heads for the 6.1

you would need upgraded springs for the stage 3 and 4.

We're going to change that VERY soon !! I fully expect to be running consistant 11's naturally. Timeslips to come as soon as the track opens and we're done.

:rocker::rocker::rocker::rocker::rocker::rocker::r ocker:

how can u order the stage 4 cam and can u supply the springs also with the purchase?

so does the stock heads handle the power of the stage 4 cam?

http://purehorsepowerperformance.com/pppcustomcamperyourrequest.aspx
Select 6.1L/370, Standard, Stage 4.


Here is the spring pack.

i ordered the N/A stage 4 cam for my car and i have the comp single springs 918 and it handel up to 600 Lift . Is this spring is good for the cam and handel the power for it ??
please tell me because i want to try it and tell u my new dyno numbers ;)

Thanks Andy

Degree this camshaft using the specs provided with the cam. The asymmetrical design of these lobes MAY not allow for accurate reading using the centerline method.

This camshaft is designed for maximum power 6.1L applications.

CHECK and verify rocker arm geometry and lifter preload.
This is imperative for optimum performance of this camshaft.

The power band is roughly between 6000 to 6800 rpm for 6.1L engines.

The preferred spring pressure is 130# -135# on the seat.
It is highly recommended to use PAC Racing 1235 or PSI 1511 “beehive” springs.
Hardened push rods required for best performance.
Titanium retainers and hardened locks required.

Headers and free-flowing exhaust required.
Flash tuning required for maximum performance.

I wish i understood all this head and cam stuff. I just fear if i went head and cam i wouldnt be able to drive my car daily and not worry about it, idling issues, less mpg, less driveability on highway ect ect. Like i said i know this probably isnt the case it just seems that everyone that buys heads and cam do radical builds that arent very streetable. I guess this is why i tend to veer toward FI like a vortec. Just strap on and go. I know this has been discussed adnosium but just giving the mild modder's perspective.

A supercharger is not strap on a go, you need to get a full live CMR tune if you want a worry free operation. Our stage 2 setup has absolutely 0 problems as a daily driver. The problem is that most people want to push the envelope with something too big and they run into issues.

Andy, Stage 2 PPP cam is on my list to use it with Wet-flow Stage 2 or 3 heads
unless you suggest another cam

That will work.

If I had the dough thats what I would buy.

I want to the biggest cam..the best for spray..with the stock heads.....

Go........

224/230 114lsa.

Yea go Andy!!!!

Need to upgrade the springs? Nice lope?

you dont want lope with a n2o grind. Yes, you can use stock springs with that camshaft.

I dont see that Cam in your Cam Sheet?

I spec'ed the largest cam i would run on stock heads for spray applications. We do not limit ourselves to what is on that sheet. You requested a custom cam and thats what I provided.

^^^^^^ and thats why PPP is awesome

Aight thanks for clearing that up....I'll be in contact with you guys for more info and priceing....

Thanks

I want to the biggest cam.. with ported heads and stock piston and stock block ??
i have ppp s3 cam
