i too wish there was an iron head for the 603 engine.

i believe that they did make a 618 or something similar, the same but with another cylinder. i believe it was used in trucks/ vans in europe.

they also built a three cylinder version that was used extensively in this country to run cooling units for semi trailers. it was sold under the name thermo king... and in an odd turn of events the sthermo king solinoid will work on a maranello starter.

i wouldnt be surprised if they made two cylinder versions and eight cylinder versions too.. for what, lawn mowers and boats?
