Re: Cam Spec's Skunk2 and Others Degree
thread digging...
Lost my camcard for my skunk2stage2, but google got me here
But, the original post got a few things wrong...
Took me a few moments until i found what it was..
Skunk2 Stage2 and stage3 cams.
Exhaus opens BBDC not BTDC, thats just 180degrees wrong....
Exhaust closes ATDC not ABDC, thats to, 180degrees wrong....

Re: Cam Spec's Skunk2 and Others Degree
i have some GSC N2 cams that were degreed and got real numbers. specs as advertised are: IN; 12mm 266 @1mm
EX; 11.5mm 258 @1mm
spec when degreed are:
IN; .484 inches(12.29mm) 264 @.050
EX; .464 inches(11.78mm)260 @.050
custom crower cams.
IN; .468 inches 268 dur LOBE LIFT .302
EX; .468 inches 260 dur LOBE LIFT .302
degreed specs
IN; .471 inches(11.96mm) 267 dur @.050
EX; .475 inches(12.06mm) 260 dur @.050
So the GSC ended up being bigger than people were thinking. they have a good amount of duration and nice lift on both IN and EX cams. the crowers are almost spot on, only one degree off on the intake side. i dont mind the extra exhaust lift myself!
