There isn't too much similarity between the two engine families at all except that to the untrained eye they are both upright six inline engines. None of the internals are the same and come to think of it the externals are all different too; blocks, heads, ignition, water pumps, etc all different as are cams, pistons, cranks, rods, and dimensions and more.
So to say there are similarities is a stretch to me at least. If there is nothing really new in the 2nd edition I see little reason to buy one. So we are still where we always were, relying on 50's information. Too bad Mr. Santucci didn't include the older series of engines as it would be good to have another place to go to get up tp date expert opinions from someone of his credentials. Not having it will insure the longevity of The StoveBolt Page and our own experts so we can be happy about that.
I am constantly amazed at the bredth and depth of the knowledge and experience on this site. And for my part I say a hearty Thanks to all who contribute so much.
