Hello, i'm new here. I just picked up a 1964 Plymouth Barracuda with a 273. I'm looking to restore the car to my specifications and put out atleast 400hp all motor. I'm only used to building 1990's honda's so i'm new to the american cars. I could get anything i wanted but with the Barracuda i don't even know where to begin to get parts.I know i can get some of the performance parts pretty easily but what about the body parts. Can someone help me out with what i'll need for the head and block to make 400hp safely? Also i want to convert the car to discs brakes all the way around and upgrade the rear end, anyone have any ideas? Thank you
