I am thinking about building a '50's style tradition '23 T.  Apparently my father has most of the parts to build one, but probably not the parts that I want to use.  I might be buying a 272/four barrel soon, and would start with that.  I have a few C4 transmissions.  I would really like to use a T5, but my father keeps telling me don't even try it.  On a side note, my father worked for Speedy Bill Smith (Speedway Motors) for around ten years.  He designed a bunch of the products that I will probably be using or buying.
