The engine is not a Ford. It is a 2.4 litre Ecotec from GM.173 hp, it would be a good choice for a Plus 4.
A few of us have the 1.8 litre Ecotec in our 4/4s. In stock trim it produces 140bhp, but with the MBE ECU it produces in the region of 170bhp. I can confirm that it does indeed make an excellent engine for a Morgan!
