Formula Ford 1600 blocks were marked 711M ...
These blocks were used in many 1600cc Fords including Fiesta, Escort, Capri, Cortina and also some comercial vehicles. There's nothing special about 711M blocks with regard to being a 'Racing Edition' except that there were a few very rare 711M blocks that were Cast Aluminum with wet liners - and these weren't used in Formula Ford 1600. If you have a 711M block, and it's in good condition then it 'could' be used in Formula Ford 1600. Cheers Engine Guy |

The 711M replaced the earlier 681F block.
The 711M will be the block used in any 1600 equipped Ford from about 1972 onwards. The differences are:- Flat head (681F are "open chamber"). Better port design (but valves are same as 681F). Thicker block walls. Stronger crank and mains caps. Because they are a thicker walled block they can be readily drilled out to a capacity of 1700cc. Could go bigger (1760) but becomes risky on some blocks due to variable wall thickness. Because these engines were as common as muck they were specified for Formula Ford (being a low cost entry level formula). In real terms, for a road engine, the only advantage is being able to safely get the 1700cc capacity.... the rest is only in the "nice" category. For competition and high reving applications, the stronger block/crank combination would be advantageous.

No, I don't. I only have a manual covering the 681F.
Someone here may have a Mk2 Escort manual. Sorry I can't help.

While on this topic, how would a complete FFord engine go in an Escort? What rev range do they use in the race cars?
