Have '66, '72, and '76 and donor truck with 6.2 chev and sm 465. Thinking of cramming it in with the dana 20. Getting about 20 mpg with another 3/4 ton with same engine and 700R4 with Banks turbo. Torque should be good and power adequate since Bronco weighs almost half. Any information about adaptation, sm465 to dana 20, or room for 6.2 under hood ?
