I'll grab frame and engine numbers sometime when I feel like getting grubby.

Not sure if the fuel pump is oe, but it's mechanical and labled kyosan or something similar.

I'll try to get a plug on that open tube on the carb... I actually thought it had a plug on it until you mentioned it.

How can you tell the year of the carb? Is it possible they were using these carbs in 77 if we both have them or is it a common replacement?

After reading more about registering in different counties, I think I'm going to try to pass the visual with what I have, an air rail and smog pump (assuming I can find both) and then see if I can tune it to pass. Trying to find all the little bits and pieces seems daunting and probably not necessary... Am I on the right track?

federal spec

front main seal leak is common. you'll need a front main seal and the timing cover gasket, along with a tube of fipg. get oe toyota...the felpro seals are crap. do at least, the lower radiator hose while you're there.

kyosan is oe.

the carb will have a number/letter sequence stamped on it...that relates to build date.

if you have an airrail, i think pighead has one, but we don't know what vintage. if we spot it see what we can find out.

I asked about the fuel pump because there isn't a return line hooked up from the carb which there should be.

A smog pump, ABV and air rail should just about do the trick for passing smog if it's running right, and good news is they're easy to find. The harder parts to find will be the BVSV, VTV, 2 VSVs and vacuum surge tank, as that stuff is specific to 77. That is, assuming you would want to return it back to the oem configuration and don't want to pay SOR prices. Do you still have electrical plugs on the driver side apron for the VSVs? Do you still have the charcoal canister?

It's probably just a coincidence that yours and mine both have 78 carbs, SOR has excellent pictures for reference.

Oops never mind you do have a return line, I just couldn't see it at first.

Yes! Rock Auto actually has decent air pumps for the best price I have found. Or I may have a non-working one that at least looks the part. You are missing a bunch of vaccuum tubing, but that may be overlooked. You will definitely need an air rail hooked up to an apparently functioning air pump. A probably a nicely leaned-out carb tune.

I have electrical connections on the driver's side apron... I thought that was where all this stuff lived? If not, I'm not sure what these connections are for.

No charcoal canister... I don't think, where does it live?

Rock auto... I'll search for that!

I hear the shop at broadway and Arapahoe in boulder knows how to tune these things to pass if I can pass the visual. That's my goal as of now... I may try to return to oe equipment down the road, but getting plates is the priority!

The driver side apron is where this stuff lives, that's why I asked about the plugs. The charcoal canister lives near the distributor

I didn't scour the passenger side as well. I'll look tonight.

Anybody have a picture of a complete '77 engine bay?
