Any help planning a build that will be cost effecive ?

Cheap ? :eek:

Off of the top of my head...
A carbureted setup saves a bunch of electrical and computer work and $$$, MSD makes a stand alone ignition setup. Jeep exhaust manifolds seem to fit many applications. A mild 727 with an 11" converter with a Bouchillon or Lokar cable kickdown solves the downshift issues. You'll need an 8 1/4" or 8 3/4" axle. A 7 1/4" axle is a waste of time.
