This is what the chambers look like. 44,000 miles, quite a few of them running crappy 87 ethanol fuel.
Piston tops all look the same burn wise, and there was this goopy sh*t on the valley pan... carbon mixed with oil from exhaust crossover?

Figured out what map I am running so that my buddy could tell me which one we should go to, hopefully that helps because she is running pig rich. Also wanted to see why the Dakotas show 14 and some change but my Edlebrock shows 13ish if I'm lucky, still not sure why yet but I guess will have to do some more digging
Have you tried turning your base timing down? I had really hard starts with too much initial timing and yours looks high in the video you shared.

Did that engine use/lose any coolant?
It did, then stopped. Head gaskets were fine. It also had an external leak as well as some green corrosion on a freeze plug.

We talked about doing that, but from their instructions we stuck it at what they call for and then can be controlled through the unit. Played with the tunes some, tried the first one my buddy recommended which went way the other way so tried a second which seemed to start much easier and didn't start off smelling rich but did at the end so we will see. Ended up moving the fuse down so the wire isn't so stretched, gonna have to redo it because i reused the crooked holes so will slide it over slightly and call that good. Still not loving the battery voltage I'm seeing on the Edlebrock but not sure what else to try there, may do a temp wire directly to the battery by itself and see what it does

Guess it can be something I did for my '81, verified my shipping info with OPGI for my dash pad. Shipping Monday, claim I should see it Wednesday. Now I'll have to see what I need to turn it dark maple & get the harness attached. More motivation to get the body up here to get that done.

Been a while since I've been able to mess with my project.. but today I installed QA1 upper arms and dropped in 455 to get some motivation going to start working on it.

Another weekend, another adventure Saturday morning I cleaned the garage up some while I thought I was waiting for someone to come buy my Sniper setup, after that I decided to adjust the fuel pressure with the new fuel map so that it should run better. That went pretty smoothly as did getting the bluetooth setup on the air ride and headlights with phone that controls the Edlebrock. Run it to Sams to get it topped off with fuel since I was thinking it was low, come back and just as I get out in front of my house it stalls and won't start again.
As I am tinkering around it is apparently a g body parade cause I had 3 different ones pass me by as I am working on the car. So while looking around I realize it looks like the wire from the starter is starting to melt some at the junction block. I feel around the wire a bit and feels like there is a knick in the jacket, while waiting for my buddy to come and help figure it out I get it to start and move into the driveway a minute before he gets there. I have him look over what I came up with, he agrees so we decide to run down the shop and make a new wire to run from the starter to the distribution block. The problem ends up that both the large gauge and small gauge wire are on the same terminal so I have to leave it for the time being but run the one we made as well. Get it running better but still having the low reading on the Edlebrock for the battery. But decide its good enough and I take it to a show that night and the following morning without major incident (had a couple of stalls here and there). After the show yesterday I decide to kill some time by cruising around until going to meet my buddy at his shop at 2 to put the transmission in the GTO.
Get .2 of a mile from the shop and the car stalls, does the slow crank for a second and then everything goes out. We end up dragging the car with his truck down to his shop after a neighbor comes offer and offers a tow strap (ended up seeing some cool stuff in his shop while finding the tow strap). I have power at the battery and the 2 posts I put to be able to jump it if it dies, but no power anywhere else so can't pop the trunk to get in there. I am guessing the big fuse I just replaced popped when the wire we made the day before must have got warm from driving and fell enough to lay on the header. So gonna have to remake a wire and run it and change out the terminal end so that I can get rid of the other wire with the knick next time we get around to the car.
