I found my Cam Card for the cam that I put in my Yenko. Where can I go to find the spec's for the stock LT1 cam from GM/Crane?

If I list the spec's for both cams, can you guys predict how my Comp Cam will perform compared to the stock Crane?

I believe THIS is your card.

Original 2182 Cam;

Lift: In; 459 Ex; 485
Dur @ .05: In; 242 Ex; 254
Centerline: 116 (I think)

My Comp Cam;

Lift: In; 510 Ex; 530
Dur @ .05: In; 242 Ex; 250
Centerline: 106

Rob/Pete/Sam;
Is there a big difference in rear wheel hp/tq between these two cams since I'm using the stock manifolds, smog pump, and Gardner Exhaust with resonators?

Marlin, That seems to be a pretty high lift cam. Sometimes your rpm's and torque are hindered with a very restrictive exhaust.Your engine can not breathe properly, hence performance is hindered. Too much cam and no headwork can hurt also. Do you have enough vacuum to stop? Sam [img]/ubbthreads/images/graemlins/eek.gif[/img]

I have plenty of vacuum, 18 at idle. The only thing I wanted was a lower C/L, to keep some compression into the engine at lower rpm. I agree the extra lift is irrelevant due to the factory manifolds, smog (not cheating!) and factory exhaust with resonators (not cheating!!).

If I could do it over again, I would probably go with the Crane since I really don't drive it that much. And, so Pete wouldn't bust on me some day at the track [img]/ubbthreads/images/graemlins/grin.gif[/img]

Marlin:

Just curious...is this your current cam (from Comp)? Check the part number & specs and let me know...
