4.6 in SN-95 same as S-197 - 4.6 motor?

[KeithB78]

Does the S-95 have the same motor, or is the S-197 motor a whole new design?

Thanks

They're both modulars and their shortblocks are very similar (though not identical) but the cylinder heads in the S197 cars are 3V versus the 2V (or 4V) mods in earlier cars.
