RE: Evolution .60NX W/ Jett Muffler for Sundowner
Hopefully it turns out to be a honker. The Webra .50 was marketed similar...but it cost a pretty hefty chunk 20 years ago. At the time, I didn't care about speed so much, just power to weight.
If this engine can turn a 9x8 or 9x9 half way decently and last for awhile, that would be great news.
