I have recently picked up a sleeved block and am now wondering how to go about making it as large as possible in the bore ... any idea how far i can take it ? where to get the sleeves from ? 1275 a+

We were prob. drunk when we set it up last and thought this will be a good idea

Unsure exactly, I just pulled down a small bore with one in it. Talked to my machinist and he said it would depend on the type of sleeve that was used.
The machine shops have access to sleeves though. With the distance between the cylinders on a 1275 I can only imagine you wouldn't be able to bore too much.

Ask GR, he does lots of A+ blocks.
Many were factory sleeved due to casting defects.

Maybe look around for another block for your big bore project ...and avoid disappointment down the track
