HI, EVERYONE! I am 77 and I love tri fives. I have had a lot of them. every body style except convertable. different yrs. I am now rebuilding a 57 4dr sedan. I have already removed the frame and replaced everything ,added power disc front and new Borgenison p/s box. I am at a loss as to weather or not installing an L/S or the carbed 350. I dont know squat about comp stuff. Is it too much or what?
