I have a set of manifolds that came off of a 71ss 350 car. I need to know if they are org. to the car. The last 3 number are 222 and 041.

I have an old book that shows RH3973432 & LH3989043 for the 71 L48 engine used in the SS350. It says this engine didn't have a smog pump.
It shows a 3989041 manifold being used on 71 Z28 with smog pump and most 72 engines with smog pumps.
I can't guarantee this information to be correct. Maybe someone with an original car can post their numbers.

Thanks Gary, the mans. I have does have porvisions for smog.

CBTN shows 3989041 to be good for '71 Z/28 only (so far as Camaros are concerned, lots of other apps going forward in '72, '73 and '74) and shows it to be an AIR manifold in '71...and NB2 (CA emissions?? IIRC) in '72, and back to AIR in '73 and '74.

I can't find a manifold ending in 222 in CBTN

BTW and FWIW, CBTN backs up Gary S's "old" book:bowtie:
