Engine block numbers

OK, I was not there and I do not know.

This whole subject is very frustrating for me!

I was there (Ford Thames Foundry Dagenham) on and off over a 5 year period. It was a long time ago and memory fades. Also my focus was on the plant engineering & manufacturing processes (blast furnace, coke ovens, foundry...cupolas, moulding lines, core blowers etc etc) not product engineering per se.

I do, however, know that some folks interpretations are way off the mark. In other words I can help with what things aren't...but not necessarily what they are!

Later....

So clue me in on what is wrong with what I have said. That way I won't repeat it and be wrong again and again.

I have 2 L blocks both on std Cortina bore size.

One has the "normal" thick L and the other a thin L.

Until I picked up on this thread i had never seen or heard of the thin L

I'll check some numbers tomorrow

Hi all,
I?m reading your contribution very interestingly.
The T number must be the group of core patterns of the raw cast iron part.
I?ve seen T20 max. also I found the T number in the cast iron gear box(T4) too.
The Alloy parts cannot find the T number.
I think that there is no correlativity in the T number and thickness.
If it has correlativity, Lotus Block will surely be the always same or close T number.
The suitable as a method of the thickness, it is a stamping grade "LA" or "LAA" rather than a casting T number.
I?ve never seen the skinny "L". Isn't it only related to the date of block?
Let's investigate thoroughly!
Thank you,
Hiro
