I was wondering what all would be involved if I got a TBI from another 1993 truck with a 350 in it and put it on a 93' 350 instead of the carb?

Just need the TBI, ECM, and harnesses?

Do the fuel lines bolt right to it?

Alright since the TBI will not bolt to a carb manifold can I use this to hook it to the carb manifold?

Yes, that will work. Just make sure your fuel pressure is correct, and the ecm chip is from a 350.

What about installation? What all does it take? Mounting the ECU, mounting the adapter and the TBI. Hooking up the fuel lines, and then just running the wires from the ECU to the TBI and then hooking the ECU to the power?


MIke.

you got it all right. that adapter is a monstrocity. I have a holley one that i didnt use, wrong one, that i would sell ya cheap. its all boxed up and ready to go back to summit but if you need it then its yours.

A little more than this. You'll need a knock sensor, map sensor, and weld in an O2 sensor into the exhaust.
Check out www.chevythunder.com and www.customefis.com for more information on this swap.

mrywillys is right. youll of course need the sensors....3rdgen.org also has alot of good info.

Ok cool. And now with the knock sensor where does that go I get the rest of it.

there will be a pipe plug in the side of the block. that leads to a coolant passage. it goes in there... mine is on the passengers side under the header about 3/4 way back

edit: 3/8 i believe

An o2 sensor would be a good idea as well, as the TBI computers run pretty shitty without one.
