Just to start Bluebird sump or even 200b sump and oil pick up off the same motor, Stumpy stanza box 4 or 5 speed and Auto 1200 tailshaft, 120y H150 diff minimum i reckon, Thats what im headin for. L20b is a tall motor they go in with some fiddling mainly sump mods. We are going L16 then up to L18 with L16 head in Mr Hanky. Gotta mod or make new mounts on 1200 cross member. We are using mounts off a stanza cross member as recommended by PIGDOG. Hes one of the best guys to talk to about it and he keeps it practical.
