I know there is a bunch of threads about this that has bits and pieces, But is there a link anyone could provide that kind of states exactly what I need to make this swap?

Also it seems like a major headache, from people that have done it, is it worth it?

 

I can't see where it would be worth it. You need the engine, the intake system, the injectors, the computer, the prom, all the wiring. PITA in my book.

If you have to stay FI because of emissions laws, snag a 350TBI - all you need is the 350, a 350 TBI prom from a caprice or truck, 350 knock sensor, and 2 350 TBI injectors - you keep your ECM, all the wiring remains, you keep your TBI unit - much easier.

 

dont you have to change the fuel pump and fuel lines too?

 

you don't need a harness or wiring. You can re-pin the connector at the pcm and you will need the tpi pcm and correct prom tho.

 

Get a intake and adapter and get a 350 tbi with injectors and bolt that on top of topic engine

 

I did this swap. Not as hard as people say. The easiest way is to get the harness with the tpi system but you can repin the tbi harness if you want. I believe there is a tech article on this here on thirdgen.org. Yes you will need to change the fuel pump and sending unit in the tank. In my opinion that was the hardest part of the swap. If you do this swap stick with a speed density system from a 90 thru 92 models. If you have any questions PM me and I'll help the best I can.

 

doesn't that defeat the whole purpose of the swap?

 

not really a tpi engine is expensive to make it into a good performance engine you can get same performance with the tbi by using a 4bbl intake with a adapter and bore out the tbi unit and up the fuel pressure which is alot cheaper for diy then tpi unless you have the money and for the amount of money on a tpi engine spent to swap and swith over you could of got a vortec 350 or a 6.0 vortec and make more power stock and use a tbi unit you maybe have to get a custom chip but thats more easy then converting to tpi
