A few months ago I was watching a race from 1986 or 87, maybe Long Beach or Milwaukee, during which there was an interview with Michael Andretti. In the interview Michael mentioned that Kraco had started its own engine program. Now I assume he meant Kraco was now building their own Cosworth's, but it got me wondering about engines in that era. Specifically I would like to know if anyone can tell me how much difference there was between the DFX's each team was racing before the Ilmor/Chevy came on the scene? I know ostensibly they were the same, but how much were teams able to modify and improve their DFX's? For instance, how different were the Cosworth's Penske was running in 1985 to the Cosworth's being run by a team like Leader Card?
