M116/M117 Intake manifolds
 

Can they be swapped? I have a beautiful EFI kit from Elbe Engineering built for the M116/M117 motors to go on a 78 450sl. The guys at Elbe were nice enough to include a throttle body with TPS sensor considering our 450sl had mechanical injection (CIS) originally. Problem is, the throttle body they sent has a smaller bolt pattern. Looks like it most likely came from a M116 motor. Will an intake manifold from a W107 380sl match up on an R107 450sl? The bolt patterns look similar, in pictures. If I understand correctly from the MB Service Manual, M116 And M117 use the same block and heads, the differences being in pistons and cam profiles. Can anyone answer definitively?
