ZZP LNF Cam Testing
Unless I've missed something, this is the closest we've come to getting specs on these cams.
The exhaust is actually increased closer to 12 degrees.
umm, really?
I just looked again, you have dyno results listed, and then this;
Please don't take offense by this, but if you don't want to disclose w/o buying, that's one thing - but I for one don't buy anything unless I am informed beforehand.
again, no offense intended - I originally subscribed to this thread in hopes of reading the specs on these cams.

He pretty much gave you the specs right there. All you have to do is know, or look up the stock LNF cam specs and add about 10 degrees of duration to the intake side and 12 to the exhaust side. Then to get lift, add .018" lift.
lmfao! tj you are always good for a laugh.

in my world, "about" doesn't cut it - especially on camshafts...
Maybe I'm an old fashioned stick in the mud on wanting to know specs - but I know for a fact that no one in their wildest dreams can order cams by asking for "about" - and having personally experimented with different cams on GM FWD cars in the past, I just figured that getting the actual specs wouldn't be a big deal.
Things I normally read are:
- advertised duration
- duration @.050
- duration @ .006
- lobe separation
- lobe lift
- lobe centerline (when installed straight up)
pictorial example:

and with that I'm done.
I know how to read cams and I understand your frustration. But I'd be willing to bet you if PM'ed a member from ZZP about it then you'd get a clearer answer. I know if you order the cams, you get a nifty little cam card that tells you everything you need to know about your cams.
ok, good to know, sometimes it seems that the general membership here doesn't understand stuff like this - instead they think everything can be done with a tune, and as a result, mechanical upgrades are often (at least perceived by me to be) scoffed at.
I would not order without knowing the specs, and I had thought that this exact thread would have had the specs posted by now ~ last time I checked they didn't actually have these listed, and they were not released yet, and I am most certainly not going to waste the time of anyone associated with a business, with questions when I don't plan on buying beforehand...
I mean, I don't even think any cam manufacturer has LNF cam blanks, and GM never offered LNF cam blanks - so even if someone wanted to pull the douche card, it wouldn't to be easy.

fair enough then.

I gave you the .050 numbers.
Lobe separation is computer controlled.
I gave you the lift.
Centerline is computer controlled.
Actually, "about" is what everyone gets when they read cam specs. We have hydraulic lash adjusters and variable cam phasers. The numbers on paper are not exactly what you get in the real world. I said "about 10 degrees" and "about 12 degrees" because we use .050" specs while GM published 1mm specs. By my measurements, our cams are about 10 and 12 degrees larger than stock. I could say they are 10.1 degrees and 11.7 degrees bigger, but that would make no practical difference. Furthermore, these cams are not for sale yet. If we release exact specs and then change the design slightly, the numbers are stuck out there to be repeated on the forums time and time again.
I am completely dumbfounded that I just read that.
Which part?
Do you believe that there is an important difference between 210 degrees vs. 209.7 degrees despite the fact that you wouldn't know the duration at anything higher than .050" lift? Two cams could have the exact same .006 and .050 duration, yet one could have 10 degrees more duration above .200 lift, but you would never know that from a cam card. People seem to get stuck on typically published specs even though they don't tell the whole story. It's similar to choosing a turbo based on the exhaust AR and the compressor trim even though a 200hp capable turbo and a 3000hp capable turbo can have the exact same AR and trim. It just doesn't seem to matter because people get it stuck in their head that they need these numbers and that is all they look for.
When we release specs for our cams, they will have more detail than what you asked for above.

don't worry I'm unsubscribing from this thread, and will know better in the future than to ask (you) questions.
thanks Matt for all the info that you have released but the Number's most people want is the HP/TQ gain lol
Feel free to ask me all the questions you want. Just don't act like a half a degree of duration makes a huge difference or that cam manufacturers give you exact numbers. Measure a few cams and you will see what I mean. Specs are off a couple degrees in most cases. On the LSJ, you can rotate the cam gear more than 2 degrees before the bolt is tight. Think of what that does to the LSA if you moved each cam in the opposite direction!
