X-flow
I have, in my shed, a 1700 x-flow destined for my baby. But, and here's the thing, I have a sneaking suspicion it came from a Fiesta XR2. How can I
tell? It's a 711M block with the engine mounting holes all drilled and tapped. Is the crank a different length? Or the flywheel a different shape? I
need to know before I commit more cash on a gasket set.
ps I do have a spare 1600 from my donor but it's v. smoky, the crank and flywheel may be useful for the 1700 though.
What do you think?

I've got one of each at home. If you were to measure how long the block is and I can see which one it's closer to.

Word from Burton Power is that they're all the same, however, as I'm finding out, that isn't entirely true, they may all be INTERNALLY the same,
but the XR2 has different mount points and also appears to have a slightly different crank end which means there's solid steel where the spigot
bearing would go.
IMHO The mount point thing isn't really a problem at all since there are so many other place to bolt it up. However, the crank end could be.
Mine is a 771M block, so it could well be that yours isn't an ex-XR2 engine. To be certain, check the mounts in the centre of the induction side, if
there are 4 then it's not from an XR2.
Chris - While you're looking at your crossflows, can you tell me the dimensions of the non XR2 engine's spigot bearing hole please?

RWD engine is 711M. Front wheel drive engine from Mk1 XR2 is 751M. So yours is the Escort lump.
Internally engines are same. As has been said, main differences concern mounting points for and on engine. These differ both on block and head. Rocker
cover is also different as is timing chain cover, water pump and oil pump.
I have an XR2 engine on bench at work. Have to confess have never considered spigot bush problem - will check. Crankshafts are otherwise identical so
your old 1600 RWD crank will be a straight swap if necessary. Gasket sets are same.

Thanks all, put my mind at rest, will now write blank cheque to vulcan engines for a full gasket set!!
Actually not too bad at £48

David, is correct that they are the same internally, however, the cranks are actually different.
The front of the FWD crank is shorter, the timing cover is shallower also (means you can't fit duplex chains). Also means if you fit a RWD water pump
then the 'shared 'bolt will clamp the pump, but not the cover.
The spigot bearing is missing, but all you have to do is buy a RWD one and press it in.
Also be carefull the ring gear is the right way round for the type of starter you use.
The differnce in the oil pump is that the FWD item has the filter angled up so that a drive shaft can pass where the filter would be on RWD
application.

Nope, see post named engine/gearbox confusion, I'd need a very big hammer to get a spigot bearing into that hole.
