I am doing a rigid frame bobber project. I am at the point where I need a powerplant. My frame is setup for an evo. I recently found a great deal on a new complete twin cam motor. My question is will it work with an evo style frame with motor mount adapter plate? I own a tool and die shop and can fab most anything but I am wondering how much difference ther are between the two. Mounting points and offsets. Also what is the difference between the tc-a and the tc-b??
Thanks

The tc a is a rubber mounted motor. The tc b is a motor with a counterbalancer located in the crank case

 

Vulcan Engineering manufactures an adapter to mount the A engines there.
