When I worked for GE one of the maintenance guys set up 5 fan blades on steel shafts on the roof of the building. After 6 months he sprayed each with a different penetrating oil and let stand overnight. He beat most of them with little luck. The Kroil treated blade flew over the side of the building with the first whack. That was the only penetrent in the stock room after that.

She got moisture in the front two cyls somehow. Cleaned it all up. No pitting yet. All the surfaces are good. Gonna rebuild it.So a 318 and a 340 use the same main size right? I was thinking of putting a 340 crank and rods and making a blue collar 340.Or cant it be done that way. Trying to use parts I already have.

You can have it balanced and make it work though. For the cost, it may be cheaper to buy a balanced rotating assembly since you are already gonna need pistons. It's worth looking at prices.

Trying to use parts I already have. 318 and 340 have the same stroke , 3.31 , the difference is the 340 is forged , the 318 is not ... yes there were some 318 forged crank truck motors ... i never saw one they also share the same rod length.
