Which temp sender did you check? There are two - one in the head that goes to the gauge and one in the intake that goes to the ECM.

Knew I forgot something. No Codes, even if I try to force the issue.
Don't have a scanner. I don't know where to get one, You need a laptop right?
Tested the ECM one and it checks out. The gauge one is busted.Which temp sender did you check? There are two - one in the head that goes to the gauge and one in the intake that goes to the ECM.
Yeah I think I'm gonna buy a ALDL cable and use my laptop. But its such a pain to get anything in CanadaA real scanner will tell you what’s going on. Pay a shop to test or buy a unit
I have tried it both ways with the same resultI watched your videos, and in the 'Interior' video, were you jumped
while your engine was running and therefore in 'Field Service' mode?
So something weird happened. I disconnected the timing advance and set the timing where it was happy, probably about 15 degrees advanced. ran nice and smooth, no surging. Figured this meant there was an issue with the timing advance. Set it back to 0 degrees and plugged the advance back in. Now the surging is gone, like completely gone. Decided to take it for a drive and its pretty smooth, just no power.
If I flatfoot it the truck struggles to get to 50kmh and wont go over 3500 rpm. Also the TBI makes a super loud sucking noise, almost sounds like its gasping for fuel. Once I parked, again no codes, and the vacuum is low at only about 18 inches. Imo the truck feels like it is not getting enough fuel or timing as when I had the timing locked in manually the vacuum was around 22 inches. Anyone know what would cause this
(I also have an ALDL cable on the way)

I know nothing about the history of the truck and have no contact with the guy I bought it from. I just know it started life with another 350 TBI and after experiencing the same issues the last guys decided to swap the engine for some reason. (talk about fix by wallet) It now has a 350 out of a same year Camaro (Roller cam then?) with all the TBI stuff swapped over in place of the TPI. So honestly this doesn't seem like it has anything to do with the engine itself.Trying to learn a little more of the history of this truck (ie: when was the last time that
it ran correctly?) I found your original post: (Truck bought with swapped motor for the right price.)
Not sure where that noise is coming from. Ill try and track it down* What is that knocking sound over the driver's side valve cover?
* What is the condition of the EGR valve?
* What is the condition of the Knock Sensor?
I did the plugs when I first got the truck. The ones I took out were almost brand new so I still have them. All the same, good colour.* Pull the plugs, and compare each one against the other 7. Are they all the same,
good color? Or do you have 1 or more outliers?
I just got a compression tester today so I will run the test when I have the chance* While the plugs are out, run a careful compression test. (Fuel injector fuse pulled,
Ignition fuse pulled, throttle held open, fresh battery, all plugs out, crank each cylinder
for 5 compression strokes, write down the results for each cylinder, and share the results.
Its got an aftermarket side exit on it. No cats only a Flowmaster muffler. 02 sensor is still in the original spot. So most likely not a exhaust restriction.Q: What kind of exhaust do you have on this truck?
