When I did my "On the Cheap Duster" project, I used Hooker headers, but the much more inexpensive headers from Summit racing would do well here. Combined with the Summit racing true dual exhaust kit, it is an excellent start to do.
Since you have an intake and a TQ carb, your pretty much set except for a cam. To figure this one out. I would like to know the following;
What intake manifold do you have?
What gear ratio and tire size will the car run when your done.
Is changing the torque converter to expensive. They are pricey things to upgrade to.
Remember, when you get a cam, bet the cam and lifter kit with the proper valve springs recommended by the cam manufacturer. Also a timing chain!
