I believe that should be 271 intake and 280 exhaust according to a current e-bay ad. According to it I believe you will find it's ground with a 111 lobe separation and with 5 degrees advance.

Somewhat close to a Pontiac OEM 9779066 273/282 advertised 200/210 At .050 .408/.407 .449/.448 111.25 106.5
I saw it stated The 066 is the mild, 2-barrel cam, usually found in 326 engines.
