I run a 396 in my 70 Nova, and a 454 in my pickup. I daily drive the pickup and have gotten 10 MPG on the road at 55mph. The 454 pushes my SWB 4x4 just fine, that being said my 396 is twice the motor my 454 is. The 396 spins 6800 RPM all day long with no hesitation, and makes gobs of power. It isn't real radical but not practical for daily driving 11 to 1 comp, .600"+ lift solid lift cam, mechanical secondary Demon 750, Ect. I would say run it and enjoy if you don't mind the milage.

Ditch the idea of a overdrive trans behind your big block, its not worth the hassle! The 4l60E won't work without expensive adapters and I beleive moving the crossmember, and a 700R4 will never hold the torque. If you must have overdrive, I would choose a Gearvendors unit or something similar. For the amount of miles I put on, >20 miles a day, I couldn't justify the cost. I just try my best to keep it running as good as possible, maintain tire pressure, and try not to get into the secondaries too often.
