My neighbor recently bought a '52 John Deere A that was froze up, tractor is now running well. When the layers of dust and grease were cleaned up it looks like the block was replaced( yellow not green) and " Power Block " is cast into the block. Can any one tell me what the difference or changes this makes.
Thanks in advance
Chris

The power block was an aftermarket product by M-H for added horspower. The power block comes in 3 sizes - A, B, C. The A is a 6" bore, 1/2" over the stock bore. The B is 6-1/8, the C is 6-1/4. This may have given a 10% increase in horsepower. The block helps if you are going to pull it. Other readers can correct me if I am wrong about the exact specs.
