If you want a good engine for that heavy KR, I have a Roy Szarafinski Corvair complete except for the exhaust. I mean complete with Ellison, prop and spinner. I will throw in the slightly damaged cowling as well. I want a bigger engine for my Panther.

Also, I'm pretty sure 3,000 rpm is a bit low - most of the VW guys seem to go for around 3,400 - 3,600.
