Exhaust is the hard part headers are available but pricy and somewhat difficult to install,factory 273 manifolds can be purchased right here i'm sure there are guys here that have some extras. Search the forsale section on this site for what you need or mopar swap meets,there are many guys on here that are building the slantys up and could give info in going that route. Whatever you do don't put a chevy enging in it or we'll find you and ruin your day. Have fun with your car welcome to FABO.
