Mark told that these water pumps (the stock ones) both push (out side) and pull (return side.) otherwise they will cavitate and can cause the motor to over heat.So I hooked them up. It was still overheating. Found out that these motors need a reduction/restrictor in the out(side) so I added one using a NAPA valve that I leave open all the time. Other types are also available from JTR Publishing. Problem solved. BestWishes For a Great New Year!!

Things in the usvislands are still a struggle. It will remain so until the view of "what's next to be repaired, retored, fixed, (you know) is over and that long drink of water signifying well done take place that things will be 'back to normal.'
The Islanders have earned much respect by everyone who is and has helped, worked we dem. As the sister in law says, we just have to admit it is what it is and go on from there...never mind she taught the locals Shakespere in Calypso 55 years ago and has been 'der ever since.

It's all good. mostly

Swapped out the fixed pressure return line fuel pressure regulator for an adjustable one. I've used them on these motors in the past with good results.

Got the MAP sensor (Manifold Absolute Pressure)
installed with four O-rings on the sensor probe,
that should seal it just fine....


Put in the check valve for the crankcase ventiliation system
with it's special rubber grommet, and the vacuum connection
for that....


And stuck the hose on it....


The only place on the block I can find for the
knock sensor was here down below the 5th
and 7th cylinders, I hope it's right....


I had to run a pipe thread tap in as the threads in the block
were pretty rusty, the sensor screwed in ok....
But it was a tight fit....

I put my knock sensors in the block drain bosses. I am not sure if it really makes much difference though. Larry

Update on my list of sensors needed for this
'93 LT1 speed-density efi system:

1. MAT
Manifold Air Temperature
This fits in the air ducting in front of the throttle body,
I found one, need to figure out where to put it.

2. ECT
Engine Coolant Temperature
I found one, now I need to figure
out where it goes....

3. IAC
Idle Air Control
This goes on the bottom of
of the throttle body, I found one,
it is installed.

4. TPS
Throttle Position Sensor
This goes on the throttle body,
on the end of the shaft,
I found one, it is installed.

5. MAP
Manifold Absolute Pressure
Bought a new one from Napa,
it needs a special seal that did not come with it,
but I found four o-rings that fit nicely,
it is installed

6. Knock Sensor
I found one
and mounted it in a threaded hole in the block,
down next to cylinders 5 and 7.

7. O2 (Oxygen) Sensor
I have one, need to weld a bung
on one of the header collectors for it.

Seems the knock sensor, that was originally on my 82 Silverado, was in one of the block drain holes. When new ones are installed, NO sealer, tape, or anything other that what comes on them, should be used. Course the truck no longer has any of the emissions stuff, other than a PCV valve; and it's far too old for testing in this state.

They won't check for anything in this state, Butch, and I don't know if I need it for this FAST computer system, but I'm going to try it, see what happens, I can always remove it later if I really don't need it...

Meanwhile....
Got the ECT (engine coolant temp) sensor installed in a port
on the left side head between cylinders 1 and 3.


Then started working on hanging the new firewall pad on the inside under the dash...

I found out that this sensor is supposed to mount in the water pump, so I moved it...




Now I have to find the right sensor for the dash temp gage, which goes in the head...

Ran the battery cables up to the firewall from the battery,
along the right side of the floor...


Now I have to decide if I want to put the cables through the firewall
here on the right side...
where I will have to run them across in front of the firewall to the starter and block....


Or run them across the front of the floor on the inside to the hump,
which put them very close to the starter and block on the other side....


Hmmmmmm.....

Meanwhile, went hunting for a temp sensor for the dash gage...


Found one at my local Napa store...


I haven't done anything about what dash gages I want to run,
still looking around, maybe go all digital ??


Meanwhile, I learned that the knock sensor would perform better
down here at this location on the right side of the motor near the
oil pan, in front of the starter, so moved it here...
