JD, I love your excitement excuberance about the car you are wanting to build. Truth is, if you want to know anything more about particular vendor's products you must call them BEFORE your car is built and have a game plan before you start spending your hard earned money. I say this, because some folks are going to sense your "eagerness to have a cool hot rod" and try to sell you everything but the kitchen sink.
You will end up throwing good money after bad as you keep changing you mind and flit from idea to idea about which way to go.
Hot Rod Works is a great company with great products, but map out a plan of action on "your build" BEFORE shelling out big dollars. Building hot rods is not cheap.
Personally make it a point to meet and talk with folks who have built or own cars that you like. Their knowledge and experience is invaluable.
