That’s annoying. I just took off a very nice numbered cylinder from my spare 08-bottom Jr engine to put on a lettered cylinder to prepare for this year, doing an unnecessary rebuilt ($$) at the same time. If we don’t need it, I’ll have just wasted money. And next year, we may want to be in Seniors. Guess I’ll just sell the fresh engine if it comes to that.
What letters are stamped in 2011-12? Any one have a list by production date?
