Re: rear end gear ration for t56

Some good advice above. My recommendation for the .5 OD T56 would be 4.56 at a minimum. Especially if you are running a carburetor still. FI allows for even lower cruise speeds and good AF ratio.

I wouldn't consider 4.88 to be out of line with a 30/31" tire either.
