270 Flywheel. Casting number 8386635, casting date Feb 14, 1957. Removed from '57 150 model GMC. Not used since resurfacing. 168 tooth, all in great shape. 6 bolt. Non-machined area painted black for metal protection. I have highlighted the U|C and BB with white paint for easier reading with a timing light. I also engraved timing marks for cylinders 2&5 and 3&4 and marked them with white paint as well. With flywheel to crankshaft bolts, but no lock plates. $100 You pay shipping and packaging costs or pick up 30 miles north of Houston Tx. This flywheel is HEAVY!
