440 crankshaft rods orientation question

It doesn't matter what hole the piston and rod are in as long as they are oriented correctly....

The piston may have a mark/notch on one side which is supposed to be towards the front of the engine when the piston is in the bore... If the piston has only two 'eyebrows', they should be on the top of the cylinder when the piston and rod are installed....

The oil squirt hole on the rod is supposed to be towards the center of the engine and the anchor slot goes toward the outside of the engine... The squirt hole oils the cylinder on the opposite bank, that's why it points toward the center/other side of the engine... Make sure the pistons are properly oriented on the rods...

Sometimes one bank of pistons and rods are backward oriented so the piston and rod are properly oriented in the engine... You can mix and match the pistons and rods on the same bank and not be a problem...


However if you want to switch pistons and rods, it's easier to do with floating rods, than press fit ones... If they are press fit rods, then I would just leave them as is and put them in the cylinders that they came out of... It's difficult to control the rod temperature in a home environment and not worth messing with... The rods can only be heated up to 517° max, because at 520° they will start to turn a blue color which will affect the microstructure of the metal in the rod and weaken it....

Plus you pointed out that the engine is balanced... Mixing up the piston and rod combination may mess up the balance, depending on how it was done...

I would just leave it as it was assembled last....
