84 s-10Blazer 2.8carb to 3.4tbi swap + california smog help

[BlazinBeast]

Here is the deal I am swaping out my poor 2.8 carb engine to a 3.4 finally. I want to go to fuel injection. I am wondering about smog problems. I know the 3.4 motor is suppost to be not aloud in California, but what really matters is what comes out of the tail pipe.
I know the 3.4 will pass with a carb. All it is bigger bore bigger stroke and bigger valves. The only thing I am kind of worried about is the cam. I am going to try at work to smog it with the carb on it. Then go and smog it with tbi. Make sure it smogs with the carb first.
Now my question is how much trouble am I going to have conveting to fuel injection. Like I said I live in California so it's real tight around here about what comes out of the tail pipe.
Computer wire harness sensors. What else am I going to run into while converting to Tbi. Hight pressure fuel line?
I have done my research on the 2.8 to 3.4 swap, but have not found anything on 2.8carb to 3.4tbi swap. I have been a certified tech for sometime so you can talk to me as a mechanic and not as a newbee.

Thanks,

Easiest way is to get a donor vehicle and swap over the stuff you need. It is not overly complicated but you do need quite a few parts.

Also I suggest s-series.org. Sierra over there just finished his swap. He loves it and says it runs great. About 4 or 5 guys and one girl has done the swap over there.

an wfi setup is going to run cleaner than a carb. a carb cannot be tuned to have every aspect of the engine running perfect, there is always something that compromised. efi is usualy tuned to pretty well perfect all around.

a tbi setup you are going to need about 14lbs fuel pressure, feed and return line. most of the sensors your going to have are on the intake (tps, iac motor, map sensor, ect. with the efi, you are also going to want to get an electronic distributor so the computer will have full controll over the timing.

while you are going to efi, why not drop an MPFI from an f-body on??? its about the same amount of work, but its a way more precise efi setup.
