Default LS7 cam?

Guys, I have what is supposed to be a LS7 cam. The only numbers on it are

206/08 ENG
5527

Can any one verify what cam this may be? Thanks in advance.

Doesn't sound like an LS7, that's somewhere around 211/230. Not a hot cam or LS6 either

On another thread someone said it may be a england green cam. The vendor I bought it from told me it was a LS7 take out. I am about to start to assemble my motor and was making sure I had all of the parts together. When I started to look at the cam I noticed it was not the GM numbers on it.
I will try to post a pic later.

5527 is a LS9 cam. Similar in specs to the LS7 but from what I understand the LS7 is a 1 bolt and the LS9 is a 3 bolt.

Thanks guys, doing some reading it looks like it is a LS9 ZR1 cam.

Would this work well with a n/a stock LS2?

Yep, ZR1 LS9 cam. I have a bunch of guys running them in LS2/3 set ups.

You asked difference in LS9 and LS9 ZR1? LS9 only available in ZR1, Camaro and CTS-V have LSA engine which is different cam.

Thanks

I thought the specs were pretty much the same duration wise anyway, lift was down to rocker ratio. But maybe the LSA is different.
