I'm in the process of getting a 71 GT, the deal is madem and if the snow ever stops, I can go pick it up!!!! I want to restore it to near original, just better wheels really. But I have a question of two on the motor, I want to stay with the Opel engine but I saw on a site once about converting it to a 2.2 l and that you can get dual side draft carbs. What is a good way to go with intakes and exhausts to get the best out of this and what can I expect to get out of the finished product in the way of hp? Any suggestions would be appreciated, thank you.
