3.4 EFI to Carb conversion

[Crazyfingers_kc]

Im looking into how hard it would be to make my engine run with a carburetor. I would buy the intake manifold and carb for a 2.8l, but how would i control the ignition and the automatic trans?
I heard i could get a distributor from a 85 s10 and run my ignition that way, but how would i time it? The 3.4 doesnt have a degree wheel for timing from the factory.
Also, i heard i could get a transmission from a 93 camaro, because its not a 4l60E, its just a 4l60.
I would get a fuel regulator to turn down the pressure to the carb.
Are these the only things i would need to do this job?

With all due respect....you are going to spend a lot of cash on a very old car and there is no assurance that it would turn out the way you want, yet you will still be out the money and the time. Why not take that money and buy something you want more and sell the car as is? Anyone who says "yeah, go ahead" will not be picking up the pieces when things go wrong....you will.

The old 2.8 in s10 trucks uses tbi type fuel injections. Many have adapted this tbi to the 3.4. I don't that would have much advantage.

I have an extra 3.4 V6 sittin in the engine stand. My plan is to leave the engine thats in my camaro in there, which already has pacesetter headers and a 252 comp cam. I want to get the extra 3.4 on the stand to run with a carbureted setup, and then swap all of the components to the cammed engine already in the camaro.

I hate having to tune with computers, and id love to have the simplicity of a carbureted engine in a somewhat modern car.

If you're looking for performance from your 3.4 why not do the 3500 top end swap on it and you'll make alot more hp.

Ive looked into it and it seems like too much work for me to do. This is the first time ive been able to do any heavy modifications on a vehicle, and i wanna start small(ish). My camaro will be a drift car when im done, and im using it as a learning experience.
