Why, yes Eric, I will need all new gaskets as this puppy was in float with a water pump for fighting fires hanging off the bottom. I think, from the condition of the cylinder and piston, that it got used once. But water at some point, got in the engine. And fortunately just the output bearing got done in by water. That's why I got it for so cheep cause it wouldn't turn over full rev. But the rest of it looks great! I'll put a couple of new bearing and crank seals and let er rip. Cant imagine what year it is, when was the last time Chrysler built these? Gas was super funky! If you think about it, bring a set of gaskets to Macs on the 23rd, and I'll trade you for another 5 hp Briggs IC for them.
