If you look at the SS/AH motors that require a "cross ram " intake almost all of them have very small offsets with more than likely runners that go straight to the intake valves, no like the Rat Roasters and NASCAR intakes with intake runners that are on the other side of the manifolds feeding across the motor to the intake valves
The offset is rule driven or they would be straight. At the RPM they run, no need for a long runner. Hence no crossed runners. Decent sized plenum especially with undersize carbs. Doug
