I have been working on restoring my 1967 for about 2 yrs. I have had another mustang several years ago. I love the way they handle My 1967 mustang was a 200 6cyl. w//a.t. but it was a gutless wonder so I pulled it and inserted a 289. I still have a lot of tweeking on it, but it is drivable. My biggest problem is it keeps heating up. Can any help me.
