TD crank timing?
 

finally getting around to doing something with the blank cylinder that andy (1705493) sent me and ran into my first snag. in my cox bin i managed to find all the parts for a good TD except for the crank. i did find a couple medallion cranks that don't seem to belong to any engine so i'd like to convert one of these to the TD type intake port.

is the timing the same? if not then what are the numbers for the TD.

is the bore the same?

should the port be made to the full length of the opening in the case?

thanks,
dave
