I've also been hunting for this info. I've tried all the normal stuff with no success. I like the idea of not needing a core, it minimizes cash outlay and down time. Keep us updated if you find anything!

I only checked into the midrange (stage 1) cam.... it's the only one I'm interested in. They also have a highend race cam (stage 2).

The HOTCAM's stage 1 cam is as follows:
Lift: (I)335 (E)370
Duration: (I)254 (E)246

Raptor's stock cam is as follows:
Lift: (I)320 (E)345
Duration: (I)232 (E)235

WEBCAM's mid-cam (80-411) is as follows:
Lift: (I)340 (E)355
Duration: (I)260 (E)232

Hope you like....

Thanks for the info eRAPTOID.

That is still a good size cam.

I had the WEBCAM 80-421 which was a I-.340 E-.355 and duration@.050 I-242 E-245

That was in my mild 686.


Do they offer a HD valve spring kit with that set-up? If not, it is something you should seriously consider! From my understanding, the Rap with the stock cam has weak springs that do not apply enough pressure, much less a cam any bigger then stock. Just a FYI.
