Thanks again.

The 711 6015 BA is a 1600 xflow block,I think you are right,somebody
has cut the top of and fitted the 4bolt crank(1500) what con rods are
fitted 125E? or 1600 these are + - 2.5mms longer or the old skinny
1500 type?

Rob,

Some more info on your block. The "T8" indicates a cylinder wall thickness on a scale of 1 - 20, with 20 being the thick end of the range.

If the front cover is flush with the deck, it could either be an aftermarket tall block front cover, or a lot more than 40 thou have been taken off the deck. The original 711M block is (approx) 211mm high.

Further to all the comments on this subject, can anyone help identify my
engine? I bought my S3 SE FHC in the US a couple of years ago as a large
pile of bits and repatriated it to Blighty (it is RHD). It is possible it
had a trick engine when new but speaking to the supplying dealer (its a long
story) at the weekend he thinks not.

Anyway I have my doubts that the block that came with the car is original to
it but would welcome the groups comments based on the following markings. On
the right hand side it simply has the 'fomoco' logo cast into the block
wall. On the left hand side there is a lot more: 'T8', 'B' above a small
circle, numbers 1 thru to 0 cast in a circular pattern with a pointer cast
at '2', 'OH 28' and finally '711M 6015 BA' which makes me suspect that this
is a 711M block rather than an Elan block or am I jumping to conclusions?
The only stamped number I can find is on the rear face of the block
(flywheel end) and this seems to read '1 1 0 0623' thought the first' 0' is
very faint and may in fact be something else. The block is painted black and
has no 'Ls' cast between the engine mounting holes. There is a luggage label
attached to it from, I suspect, a machine shop; this is printed 'Monarch'
and has pre printed information in both English and French (Canadian shop?)
with "Block planed 40 th, $60" hand written on it. The bores are 82 mm (by
tape measure, not accurately), it has a rope rear oil seal, 4 bolt crank and
the front cover, which is still bolted to the block, sits flush with the top
of the block with no spacer - has someone hack sawed a chunk off the a 711M
block to suit?

In the pile of bits there is a Weber head with 40 DCOE 18s, single groove
cams and a green cam cover.

Can you guys tell me anything from this or is there anything else I should
look at.

Apologies for the long winded mail - any pointers much appreciated.

Rob,
While you're at it, measure the actual block height. Measure from the main bearing cap split surface (inset from the sump face by about 1/8"/ 3mm) to the head mounting face. This will tell you how much has actually been skimmed from the top. Since it isn't together, you need to make sure everything is compatible.

I wasn't aware that a 711M or any x-flo block could be cut enough to bring it to TC block height. If so, you may have problems w/ head bolts bottomingout and the water passages may have "grown" and be larger than the gasket openings.

in...... could take a while.

Thanks again.

Rob

I am 99.9% sure that you cannot skim that much off the x-flow block, you will in all probability go into the water jackets , That is why the spacer or a taller front cover is required.

Sean, Roger, Arno et al.

Thanks for the help guys. I have a bit of investigating to do at this end
and will not get to it for a week or so - I'm not ignoring your valuable
advice and will let you know how I get on.

Cheers

Rob
