Hi,just bought a 98 S8 engine code AHC. The car is a non runner having dropped a valve /ubbthreads/images/graemlins/cry.gif damaging the head, piston and con rod beyond repair. question is: I can't source an S8 motor but I can get a 4.2 ABZ motor, can I build a good S8 spec motor out of the two,ie: will the 4.2 piston & rod be the same, and can I put the different cams and solid lifters into the ABZ heads ? HELP !!
