Part of the explanation is that the hp increase is for SS/GT RWD, aftermarket heads, auto transmission combinations only. Not all the '86-'92 L98 engines meet those conditions. Some do and were not touched, and some have that 279 rating for FWD already, but at 275 for RWD. I do not always understand the reasoning in the distribution of different power ratings for the same engine, so here is another example.
