Hi woodscap,
Here are numbers and props Michael Glavin has run on multiple examples of this engine. For which one he likes the best, he'll have to answer that directly. He moderates this forum, so I'm sure he'll post a response.
Menz S 21/10: 7400
Menz S 22/10: 7000
Mejzlik 22/8: 7900
Mejzlik 22/10: 7200
My guess is he'll say the Menz S 22X10 for most applications.
Hi stomper,
www.taurus-engines.net . It's pretty weak on current content right now. They're in the process of updating it soon. A price list has been posted in this thread I believe, and if you have more questions, just give them a call or drop them an e-mail. They're very helpful.
