I bought a cam at a swap meet for 20.00. The guy says it is out of a 96 WS6. Toward the back of shaft is some stamping around the cam, GMP-IBC-15-705.
I would like to use it in a TPI if it is any better.
Anyone know the specs?

 

should be this,
200/207 .447/.459 117lsa

 

Is that with 1.5 rockers or 1.6? Do you know?

 

It's a factory cam.

The factory only used 1.5 *theoretical* rockers.

 

1.5, like mentioned above.

 

Thanks guys. That's a little bigger than stock L98. It should help a little.
