Good day, I have had my 1971 Comet since I was 17. I bought it because I wrecked the 71 Comet my parents bought me, I found it around the corner from my house. When I looked at it I thought I would try my set of keys and low and behold they fit! I built it through high school then actually did it right in college at body and paint school. It has a 289, I swapped it out with a buddy one weekend along with the three speed and rear end. Later I had the 289 built by another friend swapped out the three speed for a 4 speed and put in a 4:11 rearend.
