Appears to be an original bore block, crank measures stock too. One piston remains in the block due to corrosion (it does move), others are out and included with rods. Block: 116984 Heads: 1166349 Intake: 1165308-2 Front cover, valley pan, distributor, coolant crossover, carb, flywheel, exhaust manifolds (those in the pic are for an Olds, but I have the correct Nailhead manifolds) I'm no expert on these, so please ask if you need more info or pics. Local pickup only, I'm about 50 yards off I-10 if you're driving through. Also have a vintage 364 Olds Rocket that needs to go away too.
