SVT Stage II Cams?

How's it goin?? I'm interested in getting the FRII Cams... but all I've read is people with regular foci getting them. Would you recommend me getting them for the SVT or will they even work with the SVT? I've currently got: SRI, Magnaflow exhaust, ORP, Throttle body, FS Tune. I appreciate ALL of your help in advance!!!

I dunno if the SVT would work with them without some new valves and adjustments and such.

Cams

No they won't work, the cams in the SVT are already top notch and aftermarket ones for it are VERY expensive. Just look to other mods because your cams are already taken care of.

ZXtuner.com offers regrinds of the SVT cams. He was conservatively estimating a 10HP gain with the regrind.

Hey Mike do you know what the exact specs on the SVT cams are? What clearance are we supposed to have on the lifters on intake and exahust too? I think mine need some shims...

SVT cam specs and a bunch of other links are in this recent post in case you missed it yesterday:
http://www.focusfanatics.com/forum/s...65#post1487865

ZXtuner.com offers regrinds of the SVT cams.
That was a long time ago, and I still don't know if he made any cams.
There certainly were never any dynos posted.
Again, see the above linked post for more info.

Doug- I contected him not that long ago and he said he could do still do it. I didn't have the money at the time though. I guess those spare cams will just continue to sit in my basement for a little while longer!
