Quote: Interesting.... So I always thought there were two difference large oval air cleaners, one for non N96 and one for N96.
Single 4bbl oval air cleaners were N96 ONLY. 1970-'71 440 6bbl air cleaners had 2 bases non-N96 & N96. * 1970-'71 HEMI air cleaners had 2 bases non-N96 & N96. *
* HEMI & 440+6 cars sold new in CA with N95/N96/N97 used the non-N96 base.
