| | I've been looking for a good rebuildable block. I found a nice low mileage block # B5AE, can anyone help me with Spec's on this block? I was told it Mic's out to a Std 272. I need to be able to bore it to a Std 312, what are the chances the Cyl Walls will accomodate that? Thx, David

| Ditto on what Chuck says. The 272 blocks seem to be all over the map in regards to how much they can be bored but sonic checking the cylinder wall thickness can help to determine which ones will be best in regards to cylinder wall thickness or core shift. To make a 272 block into a standard bore 292, 0.0625” must be removed from the cylinder wall thickness and if going for a standard bore 312, then 0.0875” must be removed from the cylinder wall. If the core shift is extreme, then the potential is there for offset boring which will help to equalize the cylinder wall thicknesses and use a block that normally could not be bored out as large under normal circumstances.

| | Thx men; Unfortunately thats a buzzkill, I cant check it before I buy it... It's in PA, I'm in AZ. I've had a difficult time finding a good low mileage re-buildable Block nearer me. As a matter of fact; I bought one hoping I could use it, and it had too many problems when I took it top the shop. I'm sure there's one out here somewhere, I'll be patient. In this case however the old adage "build it, they will come" will have towork in reverse! Keep it Kool, Keep it Old School, David
