O-470L vs O-470R. What is the difference?

[JoseCuervo]

Can anybody explain the important difference of an 470-L vs 470-R?

I believe there is an improvement of the -R versions, an engines can be converted.

Any insight?

The "L" and "R" are basically the same except the "L" has 4 counterweights on the crankshaft and the "R" only has 2. Charlie Melot Zephyr REngines.

Thank you.

No major concerns about an -L instead of a -R in a 182?

I belive that you can PPonk an 'L' but have to change the crank on an 'R' if that's of any interest.
