Its amazing to me you only get 6 or 7 in town. 30s are no where near too big for 3.7 gears, so you should have plenty of oomph. The c4/c6 were known for consuming a lot of power. Nice and strong units, but not the most efficient. I think I went from 57 jets down to 53 for the high elevation. I had t...

No, the engine perches are i6 or v8 specific. You'll have to swap them out.

Wires for an engine to run depends on ignition. Basic needs are coil and distributor.

Use a starter and flex plate for a 300, but the 302 trans and converter will bolt up.
