Thank you for feedback ! I've gotten a lot of interest, mostly from folks wanting to convert to a BB. all use the same language you did. One (un-named) person said you need to change the case through bolts. I cannot imagine why this would be true. What say you on this topic?

The CB may have longer through bolts to accommodate the engine mounts on the upper aft side of case. Those mount feet are not there on the BB, as all 4 mount feet are on the bottom.

Hey just looking around for a spare engine how much are you looking to get for this engine.
Trying to work out options as last engine I bought was factory new from air power. It was a process dealing with them during COVID.

Only the top hole in the upper mount legs use a through bolt. The other two attach points for each mount leg are studs.
