What changes occurred in the late 70's that lead to the Offy falling out of favor at Indy?
Looking at the starting grids, 1978 had almost half the field using the Offy and by 1982 there were none to be found.
Did the Offy simply run its course or did Cosworth and Chevy greatly increase their own R&D to move to the front?
As someone who attended his first 500 in '78 as a youngin' (7 yrs old). I don't recall what instigated the switch to mostly Cosworth power bythe 80's.
