Keeping your build all-Ford or all-Chevy is easy. Try building a Studebaker and keeping it all Stude. Tom Burns almost did it with his '27 Stude coupe sitting on the stock frame. The engine is a '63 Avanti R2 topped with a Cadillac 3x2 intake and shifted through a 4-gear manual. A Ford 8-inch, Vega steering box, Buick drums, and a few aftermarket hot rod pieces are about the only other non-Studebaker parts.
