If you have to be convinced, don't bother. The worry about suspension and brakes comes from people who grew up driving modern suspensioned cars. A 440, all iron, weighs about the same as a slant six car with 5 passengers. Not great for slaloming or the quickest to stop, but not dangerous. You can always add mods later as you wish. But like Joe says - it all bolts in. You just have to buy more stuff because they are different.
