I recently picked up a 64 Barracuda in great shape with 35k miles. It has a 273 auto and very well optioned. I am hoping to change out the 273 for more power and set it up to handle well. Hoping most of the answers to my questions can be found searching around the site but I'm sure I will be asking for advise....this is my first Mopar after countless GM and Fords.
