Line on a TBI need some quick ???

[AZ79K5Project]

Sorry - I don't have time to do a search, I need to jump if I am going to get this.

I have a line on a TBI setup from an 88. Asking is $100 complete.

1. Worth it???

2. Will this bolt up to my 350/TH350?

3. Donor engine overheated - do I need to be worried about the intake?

4. What am I missing that needs to be pulled?
Intake
Wiring harness
exhaust manifolds for the O2?
TBI
Computer?
Any other sensors?
Fuel pump - or is that in the tank (or take the entire tank)??

Thanks in advance

$100 is decent, depending on the year of your engine, the center intake bolts might not work. they changed the angle of the bolts, but you should be able to get an adapter to put the tbi on your carb manifold. needs all sensors, o2 is in drivers manifold, if you use it, you will probably need a new y pipe, they dump differently. get the whole tank if you can, itt'll have the baffle in it. If you don't want to mess with the harness, painless makes one for it.

If the 88 is the new body style, don't bother getting the tank, but the fuel pump can be installed into the TBI sending units for the older trucks.

You'll want to get everything that has wires going to the ECM less the A/C stuff and the torque converter lockup stuff (assuming you don't have a lockup TH350). You can cut the wires to both devices without any consequences, just tie them up so they cannot short on anything.

Under the dash by the ECM will be a connector that has power wires, the ALDL wires, check engine light wiring etc, just unplug it, then cut the ALDL connector off with as much extra wire as you can reach. It is easiest to just re-wire your own under-dash harness to an aftermarket fuse block, service engine soon light etc. The ALDL connector is the only part from that side that you absolutely need. It would probably be a good idea to grab the other side of the under-dash connector as well.

Just a quick rundown of sensors / actuators for you:

-Knock sensor (pass side of engine just above the oil pan, use a WRENCH to remove by HAND, or you will damage it!)
-IAC (throttle body)
-TPS (throttle body)
-Injectors (throttle body)
-CTS (front of intake to left of thermostat)
-MAP (bracket to left of throttle body)
-EGR solenoid (bracket to left of throttle body)
-ESC module (bracket to left of throttle body)
-ECM (behind glove box)
-Fuel pump relay (on firewall to the left)
-Fuel pump fuse (on firewall to left near relay)
-Oil pressure switch (behind distributor)
-Distributor (get HEI cap and divorced coil + a section of the power wire and tach wire from the engine harness)

If you can, get the fuel lines and filter from the frame up, and cut off the fittings on the frame hard line, you may or may not want to use them later on during your retrofit.

Everything should nearly bolt straight up to your old engine. If you have the old engine out of the truck, I would highly recommend that you get an aftermarket camshaft that is designed for fuel injected engines, or you may potentially run into issues later on with tuning the truck up.

The TBI setup does not care if you are running an overdrive automatic, 3 speed automatic or standard. There are minor prom differences between the three, but not big enough to cause any driveability problems.

If you can get everything above for 100 bucks, I'd definitely say to go for it. I'd be happy to help you figure out the rest of the wiring and other challenges that may appear.

The intake is easy to make fit , just wallow out the center holes , and use some RTV in the hole if you want to be sure it doesn't leak .

Have been privvy to TBI onto older heads , and older intake to TBI heads . No biggie wallowing the center holes .

The actual angle of the mounting surfaces is the same , so it sits in there right .

yep, I did the same on my 77, TBI intake to an old style 350. I had some performance issues due to the camshaft the engine had, but even then, the thing was way better on fuel, and even seemed to pick up some performance over the carb. Started every day, regardless of how cold it was outside.

And if someone t-bones my pickup while its in the parking lot , I too will have that on my old Blazer ....and a six lug 14 bolt too

Thanks for all the info. I am still waiting to hear from the guy.
