RE: superbee
To my knowledge, the Super Bee engine was used in the Curtiss P-40 Warhawk and came with a cylinder having 2 transfer ports. I have read elswhere that it used the Tee Dee cylinder and piston but have no idea if this is true. The Super Bee may have been available as an engine alone and again not sure.
More power than the Baby Bee or Golden Bee for sure but I don't think it would be significantly better than the engines currently available with the readily available double slit twin port cylinders. I also have my doubts tha the Super Bee ever came from Cox wit the extended tank.
Show us a picture of yours?
