New project ( stock suspension 275 drag radial 72 duster)

I bought this car for my 10 year old son, so he and I could do a project together. 1972 Gold Duster, 6/auto, California car, 22,000 original miles, all original paint, purchased as a roller. Our plans consist of a chromoly cage certified to 8.50, Dana and Calvert suspension, 4 wheel Wilwood discs, stock black interior, single turbo small block (r block) blowthrough on E-85. I cannot afford to build a competitive 275 car, but hoping to be able to race and have a BADA$$ on the street. This is our progress so far.
