how much hp could i get out of a cattman Cam they sell for $550...Has anyone tried this mod yet?

 

get a set from MSA (motorsport auto) specialize in z cars z31 cam set $160 and core. gotta give them ur stock ones. stage 1-4 i think but they got lots of nice stuff there.

 

cattman = JWT cams.
try to stay away from regrinds.
FYI JWT uses nissan billet blanks...(the last time i checked)

 

What's wrong with regrinds? I always hear to stay away, but never a reason why.

 

well the only way they can raise the profile/duration is to weld on extra material to the lobe. if done properly i'm sure it'll be fine...but if a solid billet is available why bother w/ the regrind ya know?...but that's your call on what you think and how u feel about it.
