Found the horn wires and tried to make those work. Think the horns are dead. Hooked them straight to the battery and all I got from either one was a weak half second beep and then nothing. So gotta order those.

Got my tail light fixed. Found the wires cut under the bumper from when some idgit was trying to be fancy with weather pack connectors at the hitch harness. Soldered that all back together and went to test and found they had crossed the reverse lamp and blinker wires. Recut and resolder and those are working.

Found the plug for the license plate light and got that connected and working.

No reverse lights though. Bulbs are good based on the aforementioned crossed wires but when I put it in reverse I get nothing. Don’t know if it’s a connection I’m missing at the transmission or somewhere in the harness but need to get that figured out.

Looks like I’ve got 3 out of 4 headlights working.

Need a couple of marker lamps and housings and bulbs and need new blinker bulbs for the front.

Once that’s all done and functional, insure and register and title.
 
Raining so I knocked some things out that didn’t involve opening the garage door.

New horns installed and tested. Found out why my one headlight and marker light weren’t working. Got those terminated and reconnected. Got one marker lamp installed as I need to find a clip and two screws for the other. Got the proper small block fan shroud installed. Got all new headlight adjustment clips and screws installed.

Need to secure the lower fan shroud, install the grill and headlight bezels, connect the parking brake cable, mount the coolant overflow, and figure out the reverse lights.

Your fan is too far in the shroud, it will still work but not as efficient as if it were halfway in

Fortunately there is another rib/flange towards the radiator in the fan opening. Mine is similar depth on my '90. I keep thinking about cutting the rearward section and ring off of it. But then I get concerned that the bottom of the fan will be too far out.
 
Did you remember to get a reverse fan for the serpentine setup?
 
It is. I need to drive it but we’ve had nothing but rain for two weeks. I also need to register and insure it but want to make it as street legal and reliable as I can by tying up all these small little details. Don’t want to worry about these things while driving and just enjoy driving it.

Im a bit puzzled on it not wanting to go much past 3000rpm though when I drove it. When I drove it I thought it was the throttle hitting the air cleaner. When I looked though I confirmed that not only was it not hitting the air cleaner but the Holley said it was seeing 100% throttle. Gonna need to do some logging and see what’s going on.
 
Yeah it should be wanting to start ripping then.

Double check your ignition timing first, and fuel.
 
I suspect timing or the exhaust. It doesn’t cough or sputter when it gets up there. It just kinda quits pulling. Runs up there hard.

I never did validate the timing with the Holley so need to set it to static and throw a light a on it.

The exhaust is 1 5/8” headers to a 3” collector that gets bottle necked to 2.25” pipe that dumps at the axle.

Yeah that exhaust might kill 20 or 30 HP vs a true dual 3" but it won't kill your engine above 3k, its probably your timing.

You need to make sure your ignition timing with the timing light matches the timing with the computer, and adjust the distributor if necessary to achieve that. Once that is done and they are sync'd, snug down the distributor bolt and make all future timing adjustments with the ECU.

You may need to temporarily lock the timing at a certain number to sync it, then put it back when done.

From Holley...

Once running, check the timing with a timing light and make sure it matches the commanded timing of the ECU. It is helpful to use the “Enable Static Timing Set” feature in the software that can lock the timing to a single value. It can be found in the same drop-down as the TPS Auto-set feature. If it does not, rotate the distributor until it does.

Once synced, CAREFULLY rev the engine up to 3000-4000 RPM and make sure the timing still matches. If it is advanced, lower the Inductive Delay value by about 20. If it is retarded, raise the Inductive Delay value about 20. Cycle the ignition power after making this change. Once the timing matches at idle and higher RPM, lock the distributor down and you are done.

Finally got some time to set the timing. It was WAY off. Far enough the mark on the balancer wasn’t even visible on the timing tab. Got that dialed in, added another 40 to the inductive delay and that’s all happy now.

Also found a problem in the switched 12v circuit on my MSD box. Guess the circuit it was on would slowly lose power or just shut off in between key cycles. So I got that fixed and happy.

Unfortunately I won’t be able to test drive it for another two weeks due to work travel but I’ve got an appointment at the dmv the day I get back to register it and title it.
 
First drive and it’s way better with the timing set right. Way better.

Only real issue is the torque converter wasn’t locking and temps climbed up to 218* before I got home. I did see 5000rpm on a wot 1-2 shift. It’ll jump to 70mph quick.

Now to review the log and go from there.
 
Think I fixed it. Had the wrong wire tapped for the converter. Had it on the full time 12v supply for the brake switch and not the 12v switched side. After a shower, lunch, and a nap I’ll take it for a drive and confirm but I’m 100% confident that’s all it was.
