Hi people, just wondering if any one out there knows how to tell the size of a crossflow engine without tearing it apart. The engine numbers are as follows:
711m 6015aa the casting number is t19.

If anyone can help it would be great, also it may help to know that it has the orig ford carb on it which is a single choke. We have been told that it is a 1.3, but the guy who it was bought off clearly didnt have much of a clue!!!!

Comper100

The 1.3 is 711M 6015 AA and the 1.6 is 711M 6015 BA mate.

Hope this helps

Hi thanks a lot m8, that does help a hell of a lot. Cheers!

No probs. You gonna change the Carb over?

willipdarling

Do you reckon it could be a gt engine??? Yes the carb will be replaced, maybe with twin webers, thats if it doesnt foul the servo!!!

I think the GT came standard with a weber carb. You'd be best of with a weber carb, to get some more poke out of her.

Yeah it is true, or re bore and stroke her to a 1600, fit a big valve head and a knife edge crank. Shell go a bit then me thinks!!!!

t19 is the cast number
think they increment every cast or summot , the more desirable ones have a lower cast number iirc

another way is look at the back of the engine where it meets top of gearbox bell housing.

1.1/1.3 the block is level with top of bell housing
1.6 block is about 2cm higher than top of housing.

this is 10 year old memories here so sorry if its wrong

the 711m was the stronger block aswell.as i remember its what people looked for when boring them out.ive got a mint condition one in hibernation in my garage.

pete1977

im also pretty sure that block was only used in escorts(just mexicos?) and some cortinas.

EvoCarl

Yeah thats what I remeber about the 711's.

also back then we just used to shove 1300 pistols in the 16's for a instant(although small) boost to compression/performance as they run the same size pistons.

Plus the MK1 Capri 1600 GT

I heard a similar one, on a 1300 the block is level with the top of the water pump whereas the 1600 is an extra inch or so higher. I was made up using this method to find out that the 1300 engine, sold to me by a chap from the AA was actually a 1600!

Thanks a lot everyone who has replied, it has been a great help to me.

EvoCarl

ahhh yes forgot you can see from front of engine at waterpump also.


Nice bit of luck on the engine

I got caught out that way too ( The water pump / block height size) When I where a lad, I had a 1.1 Mk1 with a 1.6GT Engine and Twin Carb and 4 Branch. Insured it as a 1.1 of course, and then a friendly plod pulled me over, asked questions, then took a look at the engine. Fortunately for me, he believed me when I said I didnt know it was a 1.6, but then forced me to take the car off the road, and I had to put a 1.3 in its place but at least I got of with the insurance bit. Some Plod are VERY knowledgeable! DOH
