deciphering engine codes
luke - 15/1/09 at 11:55 AM

hey all

im trying to work out the engine code on my x-flow engine. ive cleaned it up and theres 3 main numbers that seem to be of use.

711m6015AA - am i right in assuming this is a casting number as 711M is the engine type?

ID 6 or TD 6 - stamped on what looks like a plate on bottom left of the engine, cant decide if its a I or a T. if its T that would make it 77 when i was told it was out of a 70 car.

TO88075 - this is faintly stamped into the arms that the gearbox mounts onto. but TO was never used.

cheers for any help!

ahhhhhh s***

theres no number there and lots off tooling marks like someone has been at it with a file.

is this block useless to me without an engine number?

The casting number which is situated at the left hand lower rear of the block always ends in 6015 which is Ford Motor Co’s part number for cylinder blocks.

The first 3 numbers and letter identify the block model; these changed overtiem such as become beefier to handle larger capacitues and fix problems.

711M is the best 1600cc block, meaty casting and strong main caps. There was one more that was stronger and cold be bored out even further but was only available in South Africe.

There will be another casting with L or T number - this is an indicator of amount of metal around the bores hence determines how far the bores can be bored. you need to google if you really want to know.

Last 2 letters are capacity;
AA = 1300 cc
BA = 1600 cc

The two blocks differ in height, the 1600 being about 30 mm taller.

pity you didn't say you wanted to know about engine number not casting code as it would have save me some typing.

woah, ok! you saying my block is a 1300? i was informed it was a 1100 and had a label on the rocker cover saying 1100HC

dont worry about the typing! thats given me a load of info that i didnt know! thank you!

EDIT ive just looked on burton powers site and it confirms mines an 1300 which is brill as i thought it was 1100. however no engine code is useless to me! am i stuck with getting a new block then?

^^^^ I don't think so.

AFAIK there are two block types, ignoring the variants.

a 1600 block and 1300 block; the former is taller by about 30 mm for longer con rods.

The 1100 would use 1300 block. I don't know if it has same crank or bore as 1300 (my Ford Escrot book is at home) - but one of those has to be smaller for the lower capacity.

ah ok! that makes sense!

ive just measured the bore and stroke, 82mm bore and 55mm stroke.

i really should get a escort haynes!

That'll be an 1100 then..
