Guest Posted January 26, 2000 Share Posted January 26, 2000 It's cast iron and it's got a 3.55 bore that could probably clean up at 30 over. The head is aluminum. It has a cam, cause the valves go up and down, although not very FAR up and down. It has nearly a quarter inch of end play on the crank. The rod journal is clean. I can see it clearly because it has no rod or piston! I pulled it out of a rusted out relic of a simplicity that was used to move boats around a boatyard. I also have the Vickers, for whatever that's worth. Link to comment Share on other sites More sharing options...

Guest Posted January 26, 2000 Share Posted January 26, 2000 I am not sure but I think it should be a 14 hp briggs that was used in very few tractors. Good all around size engine in my opinion. ->happyjack<- Link to comment Share on other sites More sharing options...
Guest Posted January 26, 2000 Share Posted January 26, 2000 But wait if it has a 3.55 bore then its probably already been bored 30 over. The 14 is around or closer to 3.50 "but" -next guesser->happyjack<- Link to comment Share on other sites More sharing options...
