Hi guys I was wondering if anybody has purchased this cam yet for the 2200 and how is it working for you? I am still in search of a cam for my car. It doesn't state any specs but wanted to get any imput possible from the OHV guys who might be running the cam in their car. I will be building the motor for boost but will be spraying the hell out of it untill i get all my turbo parts together.

For those who don't know: here is a link.

I also know that I can get a custom regrind form crane..I would prefur input on th LZM cam. Also i haven't sent LZM an email yet asking about the cam. I will be doing that next.

Thanks for any help-Jeff

I'd say find the specs and have it reground locally. I'd guess that's basically what they're doing since they have a core charge. I'm getting a regrind for one of my projects for about $200. You might also talk to MadJack or one of the other guys with a desktop dyno program. They might be willing to help you come up with a good profile.

imo i wouldnt purchase anything from a company that wont state specs, how the hell do you know if its going to be good for your combo or not... different engines with different builds like different cams...

just go to comp/crane and get a cam from them...

Thank-You Justin, That's what I was going to say.

Many small companies might say that some one might steal their grind, but if some one wants to steal it, all they have to do is buy one. There's more to a cam profile than the intake center line, lobe centers, lift and duration numbers. The ramp profiles have allot to do with how a cam performs and the only way to get those are to measure the actual cam it-self.

As an informed consumer, I would want to know the specs of a cam so I know where the powerband lies in order to match the cam to my motor and goals for that motor.

As for their cam (and JBP's) they are regrinds, which limits the amount of lift, duration and how far the center-lines can be moved. On a regrind,you can only move the center-lines about one degree advanced or retarded, before you run into problems of reducing the lobes too far on the pressed on lobes of the stock cam. This leave the profiles fairly limited, but is not a problem with a solid cam, such as the IPP cams, which are made from a solid billet cam blank.

The stock CLs for the 2.2/2200's is 109*for the intake CL and the lobe separation is 114*(some debate here, some have been measured at 113*). This is not necessarily bad, for these CLs are good for maintaining a smooth idle, broad powerband and are good boosted and nitrous applications. The downside of these CLs is that they wont create the peek torque and horsepower figures that tighter lobe centers and earlier intake CL would create, at the expense of idle quality. A cam with tighter lobe centers (such as the IPP cams) will respond better on a N/A motor, but may trip a CEL or require tuning. Slightly higher compression will help here.

these were just some of the problems with the lzm cams for the eco (the "first" ones) being one of the fellas to install and tune them for a customer they were very poor grinds that had little thought. we ended up taking them out and i gave him a set of custom order cams and kept the lzm cams here, they're sitting in the scrap pile waiting to be taken away.

I know there around here, I just haven't looked,but do you have the stock spec avaiable? How do the LZM cams compare? I could run them through Desktop Dyno for a comparison. Mainly for everyones information. Will probably run the Comp Grind too. If Tony Schultz, from Crane Cams, gets back with me, I'll post the info on the Crane Grinds also.

I've been gathering data on the 2.2/2200 cams and re/grinds, to put together a chart for the characteristics of these re/grinds for everyones info, I could do one on the Eco cams also. It could take a while with so many posibilities for both motors. The charts would probably be mainly where the torque and horsepower peaks are at and where and how fast the power comes on. Very general info for the use of the cams.

Thanks for your guys input. Madjack that would be awsome if you took the time to make a list. Where did you get desktop dyno again? I might be better off playing with that to get the specs for my turbo cam.

I picked up dyno2000 off ebay for like $10. It's an older version, but does the same thing. However, it isn't very good at modeling boost, I don't think any of them are.



fortune cookie say:
better a delay than a disaster.

hmm thanks no tec.......I cant get a responce form LZM i sent 2 e mails and no response yet....oh well. Thanks again guys

I was just thinking about that this teh other day. It'd be nice if we could see what a particular cam might do under all motor conditions and also under boost. It's well known that different cam profiles are needed for a given build style, but for the sake of comparison, it'd be cool to see what the what the effect would be - good or bad - on a cam such as the one that Jack came up with a while back. I still have those specs written down somewhere...

remember to take the desktop dyno programs with a "grain" of salt so to speak. they are not very accurate, and to get them even remotely close you have to know very detailed information. however they are fairly accurate on where the HP/TQ peaks are in the power band givin XX cam, etc...

just an fyi for those that like to play around with these types of things.
