New look for my Barracuda

That is the setup on my kids car 69 notchback with a 318 My 67 is going to be a bit different setup. 408, OD 4 Speed manual, 3.73s I will turn 2700 RPM at 75 mph with 225s on the back. Thinking 255s on the rear on my 67 to drop my freeway RPM to 2500. Carry fix a flat and plugs, plus the 25.5" spare just in case.
