Does anyone have one for a 1974 Camaro 350 2bbl?
If it's the same part as later years, the flexible tube (aluminum) can be found on ebay.
I believe pickups used a rigid steel tube.
The tin box which is riveted to the manifold is the hard part to find.
This one came off my 78 305 2bbl.
(Unfortunately, the corners where it was riveted to the manifold are rusted away.)
Did a 74 Camaro use a steel tube or the flexible aluminum one?
Mine was thin S-shaped rigid metal tube.
Yes, but was hoping to find use one for less $
I have two original "S" tubes in my collection that look like the reproduction 6272719 "S" from the partsplaceinc.
One is about an inch longer than the other I will get you some photos.
I have about 6 to 7 original "S" tubes but most have the tapered bottom end used on 1970-1972 models. Attached is a photo of two "S" tubes used on 1973 and later models with the non-tapered bottom end. The longer one at the top of the photo MIGHT be GM # 6272719 but I am not positive. It is the same length and curvature as the NOS 3942531 tube that I bought at my local Chevrolet dealer in the 1990's (photo to one later). The bottom end of the 3942531 tube is tapered. The 1970-1972 Camaro models with L48 & L65 engines used the 3942531 tube.
The 1970-1972 307 engines were issued the 3942530 tube which was replaced with the 6272719 tube in July 1973 for service parts (not assembly line parts).
My 1974 Chevrolet Parts Catalog (July 1974 for 1973-1975 parts only) lists GM # 6272719 for the following:
73 Camaro (350)(exc. Sp. H/Per)
73-74 Pass., Nova, Chevelle (307, 350, 400)
The top "S" tube is "solid" and has some rust pitting. It needs to be media blasted.
I will sell it for $20 plus shipping but I an not sure if it is GM # 6272719.
Here is a photo of a NOS GM # 3942531 tube that I sold a few months ago.
This tube MIGHT or MIGHT NOT be a 6272719 tube. I traced it on paper and dimensioned it as shown.
$20 for the tube in the photo plus shipping plus Paypal (if applicable). It is "solid" but needs to be media blasted as there is some rust pitting.
I have 6 different tubes in my collection, 2 are known (GM # 3942531 and GM # 3946846) and 4 are unknown. I will post another photo.
