Starter set motor on the left, Mabuchi 385 on the right. I was not able to find a Lionchief 0-8-0 that used the 385. The 385 pictured is in a starter set/Lionchief engine that I modified as pictured. Lionel could so the same if they wished. I wouldn't hold my breath though. The 385 is used in the scale 0-8-0s. Don't confuse the two.
