Cox Tee Dee to Medallion conversion

I picked up a bunch of .051 Tee Dee parts that I would like to use to build a good running engine. I have always found the Tee Dee's to be tempermental. I have read that the Medallions were easier to start and while they didn't have the power of a Tee Dee, they were good sport engines. Is it possible to convert a .051 Tee Dee with the #5 cylinder to a Medallion engine by changing the crankshaft or do you have to change the cylinder also? Also, does anyone know where I can find a Medallion crankshaft?

Thanks

You already aware of most of the differences. Theoretically, no your not going to make a Tee Dee a Medallion. However, you can detune the TD and make it more like the Medallion. Even using your #5 cylinder, you add head gaskets 5-6 of them. Switch the high comp head to a stock 325 head. You could also choke down the venturi. Seeing that the venturi of the TD is bell mouthed, I have put bushings which have a small I.D. that slip into the venturi but not into enough to block the peripheral jets. I then encapsulate the bushing with surgical tubing stretched over the outside of the venturi. Now, you could also switch the TD carb body to a Medallion carb body which will assist in fuel draw but will require more parts that are becoming difficult to source. In addition, dropping the nitro can also detune the engine.
