Default Cam techie ?

Can one of the cam gurus tell me what these #s say to you?

Int open-16
Int closed-46
Ex open-48
Ex closed-14
Duration-242
Overlap-30
Intake lobe sep-105
Ex lobe sep-107
Lobe sep angle-106.0
Lift-557
Intake lift- 0.161
Ex lift- 0.146

I guess what im asking is. What do these specs tell you this cam would perform like? Or where the power/torq would be?

Post the question in the engine forum. You'll get a better response.

Are you sure they are the 557 cams? because the info I find on the 557 cams does not match what you have in your original post.


INT 20/100/42
EX 44/104/18 242
242
.557
.557
.180
.164
#538-111

I pulled the specs from the cam campare deal off the forums, I could have wrote them down wrong, I'll check again...
With the specs you came up with would you say thats a GOOD cam for mid HP/tork?
