67 Z-28 Day 2 "Trans Am" restoration

[iluv69s]

I assume I will have to tear apart the Smokey MO 302 motor before fire up. From what I remember/heard, Smokey rebuilt all his motors prior to his big auction. I believe that was in 1991, correct? (does anyone know details of this?) So my motor is more than 40 years old and best case has been together for 20 years atleast. I assume a teardown minimum as a check would be required. Any suggestions how far I should go on a teardown/rebuild ? What I should check for..and what I should do before reassembly/ fire-up? Should I replace any parts? gaskets? etc?

Thanks for suggestions/ideas...
