546/547 Web cams...?

[green_GST]

My newly acquired 1990 GSX has 546/547 street grind cams.
What are the specs on these cams? What does 546/547 stand for? I've searched and can't find info on these. I'm used to numbers such as 272 cams, 280 cams, 288 cams, etc...

Webcam 546/547 cams are actually their version of 272's. The specs are as follows:

Valve lift: .400/.385
Duration: 272*/256*
Duration @ 0.050": 206*/206*

*= degrees

You can find all this at Web Cam Inc. - Performance and Racing Camshafts

Hope this helps!!!

That's what I was looking for!
Thanks a lot!
Any idea what I can run (no driver mod) if the car is tuned (safc2, afpr, wideband, wal.255, etc to tune)?
