Default Re: Curious about the engine, :question:

Bairdco was kind enough to post this back in 2011 about the Grubee engines. Check out the specs. 38mm stroke, they were purpose built to be. These would be the jugs to be looking for, but how to ever tell if that's what you would get?. Also check out the Super Rat specs. Has 6203 bearings on the crank. HP ratings seem realistic too.
