1300 A Series block, bored to +60", was in a mini 15 years ago but was removed due to smoking on acceleration.

Was thinking of rebuilding it, but found a hole under the centre main bearing, anyone know if this is normal?

I have had a look at a 1300 A+ block and this had no hole

Some 'A' blocks have this, some dont, all A+ dont. Unless you are considering an all out race engine, I doubt it will matter much. Visard warns of thes blocks in race aplications in the yellow book

Thanks for that, only got the vizard blue book. Was only thinking of rebuilding for road use, still not sure why it started smoking in the first place, had only done about 5 thousand

For road use will be absolutely fine.

It needs serious power and/or abuse before it makes much difference and for those cars where it will be making a difference a 4 bolt main will just about make it negligible. Solid wall A series blocks are getting thinner on the ground and it seems a bit hit and miss where they were used originally.
