I have an OBD2 b18b1 LS block forsale. It's Legit and comes with a VIN. it's just the bare block nothing inside except for main caps and main bolts. Cylinder walls has some light scoring but can be bored out to 81.5MM. THis can be a perfect project. Selling for $20. I also have the pistons/rods and crank. If you want the whole thing, i'll sell it for $80.
