What is the difference between 1st & 2nd design air cleaner assm (not special ducted) for a 1969 302. Has this been discussed? Thanks, Joe

I do not think the Qjet and Holley bases are the same

Applications for the 6423907 low-restriction air cleaner are 1968 302 & 396; all 1969 396 [exc ZL2] and Z/28s produced through the end of October 1968. At that time the AIM and P & A manual shows the super-to std Z/28 air cleaner as 6423272. The '69 Body Broadcast Copy lists the production air cleaner in box # 86 as a 2-digit code. I have BBCs from Z/28s built Nov '68 and May '69 at Norwood and March '69 at Van Nuys; all show the air cleaner as '07'. '68s are '07' also.

It is possible the change to 6423272 never took place in production.

That's interesting. My 68 z28 (02E)has a bottom like dannystarr's car & & my 69 396(08E 69) has an air cleaner that the fresh air tube is 90 degrees off the side of the carb. I know it's correct but don't know about the z28. Thanks, Joe
