I'm in the process of rebuilding my 525SC and I'm considering staying with hyd flat tappet cam.
Would comp cams CB 280AH-14 be a better choise than the stock Crane?
Below are the specs:
Duration .050 232 in/237ex
LS 114
Gross lift .547 in/ex
Valve timing .006 30/70 in 82/26 ex .050 timing not listed.

Thanks

I doubt you would see any improvement with it. The specs you posted are pretty close to the stock cam. I gained about 100rpms going to a Crane 731 roller in my 525sc. It also has better midrange.

Thanks. Maybe I should bite the bullet and go roller.

do the roller...... put same cams in mine wiped out on breakin. had to break in with single valve springs..

what else do you plan on doing? Heads, compression?

I will bump up the compression a bit with .060 SRP flat top pistons, cleaning up the stock heads and probably do a hyd roller cam.
