Specs: what do I have and what do I need?

Well I am not a great tec but I would take the points out and go with an electronic ignition and then of course headers.

Someone here will jump in and help you with an intake you should use with a stock came shaft.
Or was you going to change out the cam shaft?

Allot of our tecs are hunting or working long ours !! So give them time to jump in and help you.
Is this a valiant or a barracuda you are building?
I am waiting on a 4 door 63 Valiant /6.
