Could be a HiPo, the non-vacuume advance distributor is a step in the right direction. Is the intake marked “Edelbrock” or “Tiger”?
You can check the harmonic balancer and see if it is the wide HiPo type or thinner stock type, if is wide you might want to remove a valve cover and see if it has screw in rocker arms studs.
