Hi guys,

As much as I hate muscle cars, no other cars look right except muscle cars.

So I'm back in the market for a mustang since I sold mine earlier this year.

This time however I am approaching it from a totally different angle. Rather than trying to make it "handle" like an exotic car and therefor never being happy, I have decided to treat it as a muscle car. Horsepower and traction to put power down.

Having said this, I'm deciding between a 69 mustang fastback as previously owned, or, a 67 mustang fastback.

Which one is lighter, by how much, which one has a better design for putting power to the ground with, wheelbase n so forth, which one has more available parts, modifications etc available to be a better performing car overall?

I am looking at about 700HP.
