GM still sells the 143 cam...it's actually a blueprint cam made by Crane, but last I checked it was cheaper from the GM dealer. Skip the Comp unit and go with the GM/Crane unit, trust me...all blueprint cams are NOT the same, and this thing has proved itself on the track and the dyno...

No longer available through GM and none in stock in the US. However it is still made by Crane with grind # 3863143, you can order from Summit Racing or others.

Just picked the engine up last night from a day of dyno tuning at the engine builders. End result with a .040 over 454 otherwise totally stock was 475 hp and 482 ft lbs of torque. Unfortunately the highest horsepower rating was also at the highest RPM at 6100. The bright side is it pulled 290 horse at cruising speed and 475 ft lbs of torque. I was happy over all.

Headers or manifolds?

**SS427** · #26 10-28-2005, 09:57 PM

Rob,
That was run through stock manifolds with waterpump only hooked up. No air cleaner, recurved distributor and rejetted stock 4557.

Rick ,What cam did you end up using?

**SS427** · #29 10-31-2005, 07:53 AM

Rob,
They used the Comp Cams # 11-671-4 listed as a direct replacement "nostalgia LS-6" cam. Idles slightly rough at 700 RPM and with almost as much clatter as the original cam and a great torgue curve.
