Generally Speaking...
NO
But, that's not to say that if your state does not have a visual check component of the inspection, then maybe. All depends on how close you get the fuel mapping, that you are running an O2 sensor in a feedback loop for good emissions, and have a functioning cat.
There is no reason you couldn't make a 77 CLEANER than stock utilizing aftermarket EFI, but in CA, there's no way it would pass unless you had ALL the stock components installed. On a 77, that might be an interesting challenge, though---but the coil packs of something like SDS or TEC 2 would be a dead giveaway that something isn't kosher.
It's not about clean air, it's about CONTROL!
