alright i have a 39 chrysler royal with the sitfire flathead six and 3 speed on the tree i hve to do work to get the car on the road but the engine and tranny seem to be ok for now i am thinkin of turning it into the family hotrod but have read that the spitfire engine was somewhat of an option do i have some special "performance" six what can i expect out of this motor and is there any aftermarket boltons for it such as headers or carbs if so i may stay with the stock motor and dress it up to look good if i can squeeze a little out and not spend a fortune doin it if not i will drop a 350 or possibly a 327 and auto tranny in it just tryin to make my mind up and get some plans together thanks matt
