You know they ran a 0611 headgasket and standard head bolts too?
Hmm, what Nick said could well be true for some of DJ's earlier engines. However, by 1993 when DJR was still campaigning his Seirra, the ATCC regulations had been changed and alowed for different engine specs to be run. This included a much higher rev limit than any of the Rouse and Eggenberger cars had even seen. The power figures of 600bhp - 700bhp I have seen were reported from someone within the DJR team at the time too
Plus at the time when he was competoing, it's pretty obvious why DJ talked down his bhp figures.
