SU HS4 intake manifold resized for 1275 A-series engines
If you are building a 1275-based A-series race engine and want to run SU HS4 carbs, you need this re-sized MGB manifold. I sourced this 12h1398 manifold and cut it down to achieve the correct port spacing for a 1275 head. I had it professionally TIG-welded while mounted to a head so everything remained flat and true. I had planned on it for my own 1293cc build, but have since decided on a Weber DCOE setup.
Engine is not included.
