Hello all, I just picked up a Restored 1949 John Deere AR at auction, and I didn't go down and check it out before I purchased it and went down to pick it up today and too my surprise it has a Power Block in it. This thing pops louder than my G that I had bored .90 over and I can tell its a powerful tractor. Now here comes the questions, does a original power block make the tractor a little more collectable, what type of gains do I get with the power block over a stock block, and do these blocks have a tendency to run hotter than a non power block a since I noticed that the temp gauge climbed right up to 220 in no time flat and stayed there It does have a distributor on it as well as live hydro's.
