So, I figured, I'll look thru the '67 Parts Catalog & find the answer - WRONG!!
CARBURETOR 14-30-1The 440 (non-HP) with C.A.P. c-body & Imperial carb was a Carter AFB.
The 440 (non-HP) w/o C.A.P. c-body & Imperial carb was a HOLLEY.
All other 383/440 4bbl engines are Carter AFB.
Air Cleaner FILTER 14-29-6all 383/440 with C.A.P. = 2463 985
also in '66 Catalog all 383/440 w/o C.A.P. = 2402 677
also in '66, '68 & '69 Catalogs Air Cleaner Base RETAINER 14-29-9a-body 383 (no snorkel) = 2463 959
b-body 440HP (no snorkel) = 2863 992
b & c-body 440HP (2 snorkels) = 2899 410
c-body & Imp 440 (non-HP) with C.A.P. = 2806 332
c-body & Imp 440 (non-HP) w/o C.A.P. = 2843 058
also in '68 Catalog * for some reason they list all 383s as part #2402 678 (no 2bbl/4bbl difference)
Air Cleaner Lid COVER 14-29-7 14 different BB part numbers
let's try 440 (all part numbers listed are 440 ONLY)
b-body 440HP (no snorkel) = 2863 986
b & c-body 440HP with C.A.P.(2 snorkels) = 2843 068
b & c-body 440HP w/o C.A.P.(2 snorkels) = 2843 069
c-body 440 Station Wagon & Police with C.A.P. (2 snorkels) = 2843 053
also in '68 Catalogc-body 440 Station Wagon & Police w/o C.A.P. (2 snorkels) = 2843 055
c-body & Imp with C.A.P. (single snorkel) = 2806 320
also in '68 Catalogc-body & Imp w/o C.A.P. (single snorkel) = 2806 318
Since the
RETAINER,
COVER, &
FILTER are affected by C.A.P., I believe there is a difference other than the breather hose.
filter seat diameter/height?
I'll check the '66 & '68 catalogs to see which parts were used elsewhere.
the '66 catalog lists most of the air cleaners as assemblies
