Turbo 273 ?s

you dont have to have a radical cam in a turbo motor, a short duration intake with a centerline of 112-114 would work good. I wouldnt even change cams, just mount it up and go for it. Those magnums with the turbo top design look just like the motorhome LA manifolds I saw once. Stockish LA passenger side with a T4 flange right out the top, stock driver side snakes under pan and enters the pass side on the bottom and all the gas exits out the turbo where the pass side exhaust path would be, but it would be a 3-4 inch pipe.
