anybody know the stock cam specs for a 90??
I've been trying to find it on the web, but no luck..any help would be appreciated..
 
1989-1990 SC Automatic:
Intake Valve
Max Lift: 0.245"
Int. Valve Opens: 18 deg BTDC
Int. Valve Closes: 56 deg ABDC
Duration: 254 deg
Centerline: 106 deg ATDC
Exhaust Valve
Max Lift: 0.259"
Exh. Valve Opens: 70 deg BBDC
Exh. Valve Closes: 20 deg ATDC
Duration: 270 deg
Centerline: 114 deg BTDC
Overlap: 38


1989-1990 SC Manual;
'89/90 Manuals Intake .259 Lobe lift (.448 valve lift), 194 degrees of duration at .050", 106 degree centerline Exhaust .264 Lobe lift (.457 valve lift), 202 degrees duration at .050", 114 degree centerline.

The auto spec's came from a very reliable source. The spec's for the manual's I copied off the net so i'm not positive of their accuracy.
