Starting issues... 81 Z28

[rocketman350]

Hey guy in need some input on my problems, cars a 81 z28 with 350 sb auto. I've been trying to get to start for the last week and got no where. New battery, new starter, good alternator. Try to start it with the key and I hear the starter gear engage but won't turn the motor over. I'm thinking the starter fuseable link is fried, but not sure. Need help fast!! Thanks guys
