Cam number ?

I 've done a comp test and lowest is 110 dry, 120 wet, highest is 145 dry, 150 wet, max vac is around 8", the power brakes are poor due to the low vac, car is high geared, stock converter, edelbrock dual plane, edelbrock carb, 1-5/8 headers. I was thinking more than 4 degrees, what's your opinion ? I thought the 73 360 was around 8.5.1 ?
