For $400 you should buy it. It is as has been mentioned a 259, but by the looks of the transmission it is a converted Power shift. Cannot be sure but the levers are in the proper position for a Power shift. It also has a truck Water manifold and these are getting harder to find. You would have a full flow block and it would be easy to install a 289 crankshaft and pistons and make it an R1 or R2..
