I have a set of the 288's sitting in my garage that i bought a while back, i had to do a bit of research on them to find out what they were but for the $200 i paid for the i think they will work out nicely. I got the cam card from the company an the specs are below
it will be some time until i can afford to buy the needed valve train components to run them but i will let you know when i do.

I would actually measure both lift and duration of any Schneider regrinds. Numerous Z31 guys are having issues with their Schneider regrinds being significantly off in both lift and actual duration. It was bad enough in my case that I ended up going to new billet grinds.

I mic'ed some lobes on mine and they where accurate but think I might check the rest now, thanks for the heads up.

Check the actual duration (not advertised duration) of that cams as this seemed to be where most buyers were reporting a problem. I'm not sure if it was just cams ground during a certain time frame or what, because I have used Schneider before and loved them.

Now I dont discriminate and I check ALL CAMS (both new and reground). I check all lobes before I ever degree or set-up valvetrains.

i agree this is always a good idea, ive seen a brand new cam be off. i know with the bigger companies if you call them and tell them whats going on they will replace it.
