MG MGA - Unknown eng blocks

I have three bare eng blocks ( without heads )
How do I determine what they are. TF. Mga or mgb.
Can I figure it out by measuring the cyl? Bill
Bill Mason

I don't know much about TFs, but I believe that the XPAG had a big MG logo cast into the side of the block. Not sure about XPEG.

TF blocks look considerably different to B-series. I could tell by looking, but difficult to describe.

For B-series, later MGBs had five main bearings.

MGB blocks will often have '1800' cast into the side of the block.

AFAIK MGA and 3-bearing MGB had a mechanical tacho drive off the left rear of the block.

Bore sizes would be useful, as would photos.

If you have the engine numbers, Barney has this covered:

Adding to Dave's comment all MGA engines have 1500 or 1600 cast in large letter on on left front of block. As above B ones have 1800. TF blocks diffs to all round.
