I have thirteen B series BARE blocks. One good B18 block. Most of the rest just have worn cylinders (~.005" out of round). A few have cracked cylinders, a few have stripped head bolt holes, a few have a hole in the side. Most are B16 blocks, some B20 blocks. Some of the B18 blocks have been decked for long rods and B16 crank. About half have main caps. I probably have main caps for a few others marked w/ block # if you really need them. A few have a little rust in the cylinders but they've been stored inside so most are fine. Located in northern IL, pickup only, will not ship. Make me an offer. Not looking to make money on this, would rather see them go to someone who might use them than get a few bucks for scrap.
