I recently replace the 318 with a 340 block that has been bored and built up with new or reconditioned parts. Upgraded pistons, amshaft (Vodoo Lunati not sure of the specs) timing chain and gears, il pump, ater pump, original chrysler 4-barrel intake, delbrock carb, eaders, lectronic ignition, ebuilt transmission with high stall torque converter, rans cooler, igh performance aluminum radiator. Took 360 j-heads and had them machined, alved, nd ported to match the 340 x-heads. New brakes that need to be bled from sitting and the rear-end has been rebuilt. Runs great and sounds great. The exterior has some rust under the doors and on the floor boards and along the top of the bed. Needs new window gaskets all around. Some other dings and scratches on the body. It comes with the dual exhaust with manifolds that I had removed when installing the headers, tailgate that is in better shape than the original, he original driver side door that I replaced with another one in slightly better shape, nd some other misc. parts. Would make great rat rod. Tires have great tread. Front right tire had the sidewall punctured while moving, o spare is installed right now, ut comes with the bad tire and rim. Here are some of the numbers off the block: drivers side = 2780930-340-6, passenger side = 9B340336, tamped 12.9.68. Can get more pics and video of truck running if interested, end me a message and I can get pics of whatever areas of interest you may have.
