Thread: Piston question (off set pin)

Tweet

i remember dirt track cars did this,and i don't remember my friends doing anything but changing camshaft. naturally change the firing order.

I may be wrong here but the piston is still in its orignal bore going up & down in the same maner as before I don't see the need to change pin offset If I'm wrong someone will shot me I'm sure

It loads the piston differently due to the rotational direction.

Sounds like lingfelter believes it can work either way due to the fact he states that some people run them just like you are for small increase in HP with some piston slap while cold at start up........you might see a difference in wear over the years and it might shorten the life of the engine a little.

Sounds like it will work either way,I would let the engine warm up for a longer time with it the way you have it now,before I hammered it down.

I am no exspert ,I am just basing this on what was posted and how much work it would be to swap them.....sounds like almost a complete rebuild to swap them over.

I am not positive,depends on the build ,but I would be more worried about the oiling of the bearings due to some of the oil holes on the crank are chamfered to the trailing edge for improved oiling.....just listen for piston slap when you fire it up and determine how bad it actually is slapping.

In the end it`s your call on what to do.......sounds like it will work either way at the exspense of a little more wear on parts.
