Looking at a Tpi setup...

You guys think I should go check this out? Will it work on my 350?

That will work on your 350. If you have a pre 1987 350 you will need to elongate the middle holes on the intake, it's a pretty easy mod. If you can get that TPI, with the harness and computer $200 is a steal. If it's just what you see the cost will add up quick when you go to buy everything else.

When I did my TPI swap I bought the whole car and it saved me a ton of money as I discovered that I could make most of the stock parts work.

So what all would I need out of the car? I'm going to e mail him.

I need:
Tuned port injector manifold
Harness (Where does it start and end so I can find it?)
and computer?

you'll need, harness, fuel pump, 350 injecters, 350 knock sensor, 350 computer or a 350 prom burned. I've got a few of these cars and still in the learning process, but this is what is needed from my reading and research so far, i'm sure russel or someone else will chip in.

Soooo the computer out of his car will NOT work?

[vern350]

pretty sure you need a 350 computer, or the prom of the 305 computer burned to 350 specs. A 350 car would be best. Someone correct me if i'm wrong, but i'm almost 99% sure.

ah ok then

The computer WILL WORK.
I put a TPI off a 305 on my 350. You will need a 350 knock sensor, not a big deal. I set my TPI up, and then I sent my chip from the computer off to Brian at tpichips.com and he burned it to my specs for $50. I told him my injector size, engine size and engine details as well as what I took off for factory smog, he burned the chip and the truck ran great. I also sent the fuel injectors off to a place to have them checked out and cleaned.

To support the 350, it would work better if you consider an upgrade on the injectors. The 305 units will work, but you will suffer on performance. The Delphi "wafer-disk" injectors that came with those TPI setups were troublesome and could cause some running issues, if they are not cleaned and refurbished. I gave my injectors up for a set of upgraded Bosch "Pintel" design injectors sold by FORD racing. They work great and are smoother than the Delphi units. I put a set in my 95 Impala SS and also a set on my TPI unit that I am putting in my 91 Silverado.

A little more info. I bought a factory Helm manual for the car I pulled the TPI off and used it to trace my factory wiring harness and eliminate whatever I didn't need. The factory harness looks like a mess at first, but once you dig into it, it's rather simple.
chevythunder.com is a great site for more info

I have found another guy selling the complete tpi setup off a 350 for 360 bucks, would that be better or should I go for the 305 Tpi setup for like 160 bucks?

305's have 19lb/hr injectors, 350's have 22lb/hr injectors, a simple bandaid, get an adjustable fuel pressure regulator and bump the pressure till you get it runnin the way you want it to.

www.TPIS.com there a shop about 45mins from my house and the specialize in this stuff. ge there phone number from there website and talk to Jim Hall, he can probably answer all your questions.
