    In my opinion the best cam on the list you posted is the C118. This is an old KB grind but it works great in a 70 455. It has a slight lobe at idle, it idles at 800 rpm and pulls strong to 5500 rpm. The C118 camshaft is very easy on the valve train. We use to use this cam in many muscle car shoot outs where it had to retain somewhat of a stock idle and produce 15 plus inches of vacuum. We dynoed this cam in a 70 GS Stg1 engine and it picked up 25 hp over the factory stage 1 cam. Dave Knutson and I used this cam in the Car Craft Real Street Eliminator shoot out some time back in mid 80's I cannot remember the exact year. The car had to be pretty much stock including the Qjet carb and exhaust manifolds, the car turned consist 13.30's at 105 mph in the quarter mile.

    X2, I loved the 118 in my first motor. Just not sure Jim even wants that much cam.
