Hi,
The engine is Ford Pinto 2.0l sohc engine that is fitted to a Ford Escort Mark2 road rally car. The spec of the engine is not massive. It is running 10.5:1 static compression ratio, 285 degree cam, twin side draft weber 48 carburettors. The head has bathtub chamber with the spark plug pointing towards the inlet valve and in the direct path of the incoming charge. The following is a photo of it in the early stages of home porting.

Tom
