1231738 Block 1231786 Heads....will pull valve covers for date code if serious. 1231718 Intake not on it now. 1386003 Intake on it now. Went I put it back together I could not fine the 1718 intake so I put on the 69 430 6003 on it. I pulled this from a wrecked 70 Electra that had 59,000 miles on it. I took the heads and intake off. Heads were cleaned and magged at R and R machine shop in Huntsville Ala, and reassembled. No broke bolts in heads or timing chain housing. New head gaskets, water pump, timing chain, oil pump gears, cam, lifters, push rods. The rotating assembly was checked and everything looked great. It ran good before freshening it up. No carb, dist or exhaust manifolds, or brackets....just crank and waterpump pulleys. Has motor mounts. I spent $300.00 on the heads. $250.00 on cam, lifters, push rods. $750.00 Preferred picked up in Huntsville Ala Will Ship. Will deliver for gas and time within 250 miles of Huntsville Ala.
