I just pulled old 302 and swapped in a 351W last weekend. From experience, pull engine and tranny all together. Make sure to unhook the throttle cable and injector harness/firewall to rear driver side head. Jack up the front of the car a little bit (about a foot). to give yourself a little more engine tilting room. Drain the tranny and a load leveler comes in handy. Also if the load leveler won't angle it enough, a ratchet strap looped underneath the two front header tubes and over the engine hoist will help tremendously. Also remove shifter after tranny is drained. Just make sure everything is disconnected, and pull her out. I pulled and replace mine by myself. Major pain in the butt, but it can be done. Just take your time.
