F44 option: EGR?

[sixshooter798]

I have a 1977 C10 with the F44 option... does anyone know if this is supposed to have an EGR valve?

From what I understand, the "heavy half" trucks did not have catalytic converters, but I'm not sure about an EGR valve. The smog places here in SoCal are giving me a hard time about this stuff for the first time in about ten years...

I still have the original 454 from my 77 gmc with the f44 package ,also had cali emissions , I'll check to see if it had a egr valve , it didnt have converters but did have a smog pump ,

The answer to this question is no.

California emission C10's did NOT come with an EGR valve or catalytic converters. Anybody else in California that gets a hard time from their smog tech should point out their GVWR on the vin plate in the doorjam.

It may not matter whether or not the F44 option is there. I spoke to the smog tech today, and for light trucks year 1977, GVWR over 6001 lbs cats and egr valve are not required in California.
