The biggest concern with Stock Eliminator in terms of rules has always been the engine. If you have a winning Stock-legal car, the driveline has been tweaked, the suspension has been figured out as if by NASA, the auto trannys are super secret. Clutch pressures are usually pretty closely guarded. Because making the whole car a perfectly integrated system makes them fast. The factory manual trannys simply got broken too much and the Jericho fits everything and actually levels the field a little. So it was a good move. Last I knew, a stock eliminator 727 were fully rollarized, had C4 internals, and a special valve bodies plus a tunable convertor pressure feed. Makes the Jericho setup very cheap when compared to that witha $1K+ custom convertor.
