'77 F150 351M Smog Parts
Moved with my truck from Montana to California. (This truck was not originally sold in CA.) Took it to the shop yesterday for smog inspection and mechanic says parts have been removed, presumably to improve mileage, etc. Here are the parts he says it needs. I'm not having much luck finding them.
EGR Vacuum Amplifier
EGR TVS (throttle vacuum switch)
Load Control WOT (wide open throttle)
Delay Valve
So I guess 1. do you know where I can find them, and 2. are these for certain required on trucks not originally sold in Calif?
I didn't see them on Bronco Graveyard's or LMC Truck's site, but I'll phone them. Mechanic said to get Federal, auto trans, heavy duty. Otherwise, the truck runs great, so it's definitely worth repairing. Also. mechanic says he'll charge $150 to set it up once I get the parts. Not bad.
Thanks.

To my knowledge most states require the vehicle meet that standards of when the vehicle was built, including it's anti-smog equipment (catalytic converters, air pumps, etc.). Up until 79, light trucks had little or no smog control. In 79 they got catalytic converters.
This is why the F-150 was created - a "heavy half ton" over 6000 GVW, the F-100 was under 6000. GM and Dodge did the same thing.
The last year of trucks with no cats was 1981, some heavy GM 1 ton crew cabs with 454's didn't have cats.

The 75-78 49 state trucks under 6000# GVWR and all California trucks had cats.
