<VV> Yenko Stingers

[Cliff Tibbitts]

My March Communiqué finally arrived.  I've been accusing the wife of hiding
it until I fixed the leaky toilet, like an operating flush toilet is more
important than working on a Corvair.  

Anyway, I enjoyed the articles on the Yenkos and got to wondering.  Can
anyone tell us, just what they did to get the different HP ratings?  I'm not
interested so much in all the body modifications, but rather just what did
they do to the engines, especially the Stage I and IIs.  

Just wondering,
