While those are Super Cool, and/or Quite Fancy, not to mention WAY MORE Gooder, I'm building a Legal Eagle for a reason, not the least of which is to avoid a costly divorce.
I think that Iron liners in Aluminum cylinders are quite up to the task, and possibly Gooder from a classic, true to the original intent perspective.
If I ever collect on my wife of 33 years life insurance policy, rest assured that there will be fancy cylinders, fuel injection, and a number of other Gooder parts on my future RV-8........(as always, I crack me up)
Hopefully Scott has some perfectly serviceable less gooder parts not listed on his price sheet!
