I haven't been able to find out the specs of the cam used in the 55-57 308's. I understand they used hydraulic lifters.

1955 308 is a solid lifter cam 306344 same as all engines from 1948 to 1955. 1956 was the hydraulic cam 309742 which was replaced in a lot of 56 cars with the 306344 cam because it was noisy and ruined the timing chain. Walt.
