The engine I've bought is an old British Ford Essex 3000cc V6 a basic push-rod engine. It's heavily built cast iron because the block was originally designed to be both petrol and diesel. I thought that this block would be ideal to explore the idea I’d had that if an engine was built with the compression optimised y to run on ethanol, it would be much more economical and powerful than any FLEX-fuel and most comparative petrol engines. The engine was originally designed in Dagenham, Essex in the 50's. It's got a distributor and has a carburettor so a purely mechanical engine. It did 20 to 23 MPG and was optimized for 4 star petrol in imperial gallons.
I had the crank machined and a re-bore done at Cornwall Engines to make the new parts fit together. The engine is quite large displacement for cars in the United Kingdom at three litres and it’s now 60 thou over-size, but it's far from cutting edge. I've replaced the pistons with those from a 200 cubic inch Ford straight six and six of the con-rods from a 351(W) Ford V8 and had the crank reground to 3.1 inch.
I've had this engine assembled of Ford parts doing only machining to make them fit together. The head is completely flat as the engine was designed as a Heron type
