Don't short change the man John. Top flight shocks alone won't make "a still stock 76 280" into a modern supercar. 
  
This is only after bushings, springs, camber plates, adjustable LCA's and TC rods, strut tower braces, maybe some chassis stiffening, ball joints, etc. Did I mention tires and wheels might have a factor as well?

Read John's posts from the last few years and you'll get a fairly complete education on transforming the lowly S30's handling.
