Unhappy No emmisions

Hope someone can help me out,
I resently purchased a 77' Chevy K10 which the previous owner ripped out all the emission crap & registered it in AZ. My problem is, I live in California and I need to get it smogged. Currently I have a 400sb with a edelbrock 3701 manifold and edelbrock 1903 795cfm carb, and my question is "What else do I need to pass emissions?" The GVW is 6200 so I know I don't need cats but i'm lost after that. can anyone help me with a list of parts that I need. Any & all help appreciated.

Hmm..on a K5, I'm not sure...but I know that the #3701 manifold will pass (same one I'm running). Just make sure you've got a factory air cleaner, with the THERMAC system, and a heat-choke-stove tube in place. You'll probably also need an AIR pump, but I'm not sure on that...refer here for a better description...

My bad, maybe if I could read the english language correctly, I would have read that right the first time, hahaha! Hmm..my buddy has a 77 C10, I could ask him next weekend what kinda smog equipment it takes to pass...

Move to a different state.

It needs everything it had stock. Start by looking to see if it still has it's emissions sticker on the core suport.

At the very least it's going to need EGR, EVAP, PCV. Probably needs cats and might even need a Air pump. You basicly have to put it to stock or have C.A.R.B. # and they will check.

You WILL need the air pump and injector tubes, as well as heat riser butterfly-plate hanging off the pax side exhaust manifold, and the PCV stuff. You could probably get away without the heat riser going from the pax manifold to the air cleaner but safer with. If I get time I'll take a pic of whats left over from my stock setup on my CA registered 76 K10. I've just removed the Air Pump and associated BS.

Thanks everyone,
Not only did the previous owner remove the smog gear, he removed all the stickers too, got them on order though. I tried to price an EGR valve for it and the parts guy doesn't show one made for the 77' K10? I looked up parts for emissions on another site and they show the following: A.I.R. pipes & manifold (got headers with the ports in the mail), air check valve, air pump (got one off a 396cid el camino), vacuum valve, cannister filterair cleaner temp sensor, thermal air temp control valve,vacuum moter,vapor cannister and a EGR gasket (but no valve)? Does all this sound right?

Wish I could move to a non-smog state, CA is killing me on emissions and the price of gas $2.19.

If I were you I would start making calls and check on the rules about how much money you have to spend to get the vehicle into smog specs for CA. I know for sure there is a specific cash amount that, after you have spent money up to that amount, you are eligible for an emissions waiver. So before you go spending 4, 5 , 6 hundred dollars, just to find out you're still failing for a carb that needs adjusting, blah blah blah, find out how it applies to your vehicle. I don't remember if the cash number is a set value or if its a percentage of the value of the car vs year & model. I'm not even sure if the money your spending on replacing the items that came on the truck for ones that were flat out missing would even apply since they were removed by the guy in AZ. But it can't hurt to ask. It would atleast let you stretch out the cash outlay in parts and tuning for a full year. Just save all your reciepts incase some pinta head starts askin questions.
