I am looking at buying my first classic Mustang. I have been doing research for the past few weeks and finally feel like I can start looking at some Mustangs. The thing is... I like driving manuals and much as automatics. Which is more fun to drive for the classics? Auto or Manual? The reason why I ask... The one I am looking at is a 66' (coupe) with a C4 in it. Also has a hotter cam, 600cfm carb and an intake mani. I am wondering how much power will these things throw down with these mods. I am assuming the cam isn't too wild.
