There are much better choices than that Clifford-marketed cam and much, much better vendors. Tell us about the car, the engine configuration and how you intend to use the car.

transmission?
rear axle gear ratio?
tire size?
intake and carburetor?
exhaust?
calculated compression ratio?

If the 10:1 is true and you're willing to go with a high stall toque converter I would use a cam with around 230-234° duration at .050" lift and 6-8° less duration on the exhaust side with no wider than a 108° lobe separation. I would install it 4-6° advanced.

Do you have oversize valves and porting work done? This engine will really respond to head work. Heck, my '67 Valiant with a stock cam responded very well to a ported head and supporting intake and exhaust modifications.

Many of us use Oregon Cam Grinding in Vancouver, Washington. You can send your cam to be reground and keep the oil pump drive gear and the driven gear together.
