Big Block bracket I.D. ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The orange bracket next to the compressor? Air pump possibly? The truck is a 69 that is quite original yet.
More pics will be in a junk yardin thread...

smog pump is correct.

**too much stuff** · 04-13-2009, 09:26 PM

Would that normally be listed on the spid?

My 72 BB burb has the factory smog pump but it is not listed on the SPID. On another thread they said that all BB burbs got the smog pump automatically but I am not sure about the trucks.

My 71 bb truck did not have the smog setup on it from factory, but a friend had a 69 that had the AIR equipment still in place when he got it. I have seen both ways and believe it depended on plant of manufacture possibly.

my burb had it, 72 big block

1/2 ton trucks (some) had a smog pump... 3/4 tons did not.

Longhorn Man · 04-14-2009, 04:32 PM

some 3/4 tons did, my burb was a 3/4 ton originally.
However, my friend's 72 3/4 ton big block cheyenne super didn't have one.

Weird. My 3/4 is an original Calif truck, still has emissions labels and all, Calif Registration on the SPID....but no smog pump, and no EEC.

I have seen documentation that ALL '72 1/2 ton (and all '72 BB Suburban) 402's had smog. Also the 1/2 ton Big Block was not available for sale in California in '72. I do not have info. on other years, only the '72. Also, my SPID does not mention the AIR system, but the build sheet has a line labeled K19 AIR INJ REACT.

The truck is a 69. It is also a 1/2 ton. There is a picture of the spid on my "junkyardin" thread.
