I don’t really know the history on this engine. It was the grand prize at the 2007 Rossi Goat Ranch roundup (www.inliners.org/events/Rossi07/Rossi%20picnic%2007.htm). I’m running it on a test stand right now. I want to make sure its OK before I put the effort in to install it in my 53 3100. I expect it is stock though. You’re right, $8 is not a huge investment. Its cold and rainy today, and I’ve got plenty of other chores to do, so I’ll pick up a couple of lifters this week and try it next weekend.
Thnks for the advice,
Leon
