well, I run their ZZ9 roller which is not near as big, but from what their catalog states someone runs this cam (the ZZ-X) with their miniram on a 350 and ran 127mph @ 11.15 in the quarter....looks like the dyno was 4.65.1 crank horse power @ 6500 rpm and 411 foot pounds at the crank (engine dyno) at 5250/5500 rpm.....must be a decent cam..
looks like 290 during on intake/exhaust with a .558 gross lift on both sides/112 lobe sep.
127mph is a hell of a lot of trap speed on a 350. I wonder what gear and heads were used.
seems like a lofty number for a 350; they advertise that in their catolog which means nothing w/o knowing all of the facts; yes, it could have been sprayed or whatever.....127 mph is laying it down pretty hard in the 1/4!
it looks like it does have a long duration and probably makes power on the upper end of the RPM scale making it more suitable for a miniram intake...but I know if I installed that cam in my car even with the AFR/TPIS heads (187cc) and miniram I run, I don't think I will get 127mph in the quarter even with a new tune to accomodate it.....as a matter of fact, I know I wouldn't.
I like their parts, though! I will go on record to say I am a TPIS supporter b/c if not for them us C4 builders may have to abanden the hobby and go to C5/6 cars.....or something else....they do some neat stuff there!
I am pulling my 1988 L98 out next weekend then dropping it off to Baileys Machine. I am leaning towards the ZZ9 cam but am not certain it is the right choice ? I have SLP runners, gasket matched ported. Gasket match ported stock intake manifold which I'm told by some is a waste of time ? And the same ported plenum. Stock TB as I have been told no need to go any bigger. Having a roller rocker kit put in. Hypertech power coil from Summit. 24lb Bosch injectors. J.E.T. can't sell me a chip without the cam specs so need to decide soon. Long tube headers and Flowmaster hi flow cat and mufflers. I just want it all to WORK ! I fear the chip won't work and I will need a Dyno tune ? A shop here in Phoenix told me minimum $1,200. God I hope the chip works ! My reason for changing the cam is for HP gain. 30-40HP gain would be great. I also am putting a undersize pulley kit on the engine. I am hoping all this stuff put together will give me 300-330HP at the crank. A top speed of 165-75 max RPM 5,500 is my goal. This is a street car not a track car. The headers are emissions ready from Summit. I am so close to just going back with the stock cam to avoid the $1,200 tune and live with the other changes to boost my HP.

Forget the Jet chip and the 1200$ tune
Call Wongs performance in portland he will take care of you and get you going (TJ Wong). Guys here can help teach you how to datalog to have him touch up the tune if need be.
Port matching maybe better than nothing if you can do it yourself. To pay someone, no. Fully ported top to bottom worth it depending on your wallet/expectations
Has anyone been using this lately? If so what size engine and performance gain did you see.
I have the zz409 and am completely satisfied. The only draw back is hard to start and idle cold. It gets better once it warms up. I did know this would be an issue before I installed the cam. I'm sure the zzX would be even rougher to keep and start at idle. If you are driving your car on the street or use it for cruising, I would not use either of these aggressive cams. I would go with the ZZ9 for street use.

I was running the 280XFI. It was tune to idle just fine and starts up just fine as well. You need to give it a better for those areas.

ZZ9 is fine for your mods. I agree no jet chip needed. Your combo looks good. Make sure you get harden pushrods and guide plates too along with match valve springs
Go here if you can't find someone local to get you a prom

Cam Lobe Separation Angle cannot be tuned out. It's the nature of the beast. I had my car dyno tuned to get everything to run as efficient as possible.
LOBE SEPARATION ANGLE: This is the relationship between the centerlines of the intake and exhaust lobes. A 110-degree lobe separation angle means that the peak opening points of the intake and exhaust lobes are 110 degrees apart. This is ground into the cam and can't be changed without changing cams. Lobe separation angle is another way of expressing overlap, which is the term formerly used by cam manufacturers. Overlap is the amount of time that both valves are open in the same cylinder. When both valves are open at the same time, cylinder pressure drops. A cam with 106 degrees of lobe separation angle will have more overlap and a rougher idle than one with 112 degrees, but it'll usually make more midrange power.
