I have read several statements that talk about it being worth alot less because it is a T code. I agree with this to some extent. A K code 65-66 Mustang is rare and worth something, IF it has a stamped motor and tranny and has not been changed in any significant way. Anything else is a 40 year old car that ANYTHING could have been done to. Obviously a T code with a V8 is modified, but there is no real way of telling what has been done to an A or C car. Personally I would pay more for a T code that has all the documentation of modifications that I would an A or C without documentation. Without stamped numbers or documentaion you can't really tell if a motor, tranny, rearend, suspension, brakes etc. are original or not.

In summation, when someone says "my car is all original" I ask "How do you know?"

 

Youll never get even close to 15 cuz its originally a 6.Sorry but thats just they way it is. Like everyone else already said even if you do all that stuff you said youre going to, youre prob looking at 8-9
