Well, I feel like I got my smog figured out and I am jazzed!
I have been working solidly on a smog issue for my Airsteam and in doing that finally found the "Source" for Smog/emissions equipment for my van!
Here is the book I was directed to, and bought.
here is the page that tells all!
So, my van "original" GVW according to the plate is 6400lb.
Its a California van, so it should have 2 Barrel carb, PCV, EGR, SPK, and EVAP.
I was fretting thinking I was missing Cats and Air injection pumps and a whole bunch of other stuff...
Looking closely at the engine, I have the EGR, PCV, and the SPK(I think). I can see a Evap canister, so just need to be sure its connected properly, as with all the pipes. I have a 4 barrel carb fitted, as well as aftermarket headers so am gonna hope that I can get that thru...
