84 K20 "Ethel" Not an Sbc/NV4500/241C

Semi restoration of a 1984 K20 pickup.
5.3 LS, nv4500, np241c.

Lol well this motor has 300000 miles already so in the 6.2 world that means it's a good block I guess. And as I mentioned it has to run good first then I'll figure it out from there.
One intresting find was the oil pan has a huge dent, I'll have to deal with that somehow. This was my buddies highschool truck so it has seen lots of abuse.

You have some pics of the HVAC system under the dash? 
Your buy your hazmat suit to start cleaning that yet?
I should! I'll be wearing respirator and gloves with a long sleeve for sure.
What does the box on the passenger side look like? And the control panel?
Any idea why there's a piece of iron bolted to the clutch pedal?
No idea
I can see a couple of errors actually. Right at the top you have the first gear ratio on the 700R-4 as 2.84;1. The correct ratio is 3.06;1. The other "error" is the final drive on the 700R-4. It's not really an error though. Sure the final numbers are a ton lower than a SM 465...but unless you like killing transmissions you do not ever tow in overdrive with a 700R-4. Therefore the final drive numbers with a 700R-4 in your example are even higher.
I have a C1500 with a 6.2, 700r-4, 3.42's and 28" tall tires. I towed our 17 foot camper trailer from Vancouver to Edmonton. The trailer might weigh 4500 lbs max, and it was a struggle. This was through the mountains of course, but not Colorado altitude. It made the trip, no nuns or small children died, but if I'm honest it was a horrible trip from a towing standpoint.
In naturally aspirated form a 6.2 is not a good towing engine, add lousy gears, or a SM 465 and it gets worse. Add hills, or altitude and it gets worser. Like I said, I like the 6.2 (not sure why either) but I can't recommend one for towing with a clear conscience. Fuel economy...hells yes!! cool factor...damn skippy!! Off road...wicked pisser!! Towing...uh no.

All good points. Again, I apologize for how that came out. I didn't mean for it to be nearly that snippy.
I'm not sure where that 2.84 number came from (the almighty interwebs, I'm sure
), but 3.06 is what I have seen posted all over the place. Not sure how that got screwed up (it's been 2 or 3 years since I made that chart). Staying in 3rd gear, the difference between the two is 80RPM. That may or may not be significant, my point was that if you're in non-downshifting country (like my area), the rig should be fine, as you won't be leaving top gear anyway). If you're not, you may want a better rig.But either way, there are worse rigs out there, and I've driven a few of them. That rig may be slow, but it should have good brakes & suspension for hauling jobs. Going slowly is annoying. But being unable to quickly stop (or having overly soft suspension) is a safety issue.
Yea, I would agree with that. If you want to tow with this rig and a stock 6.2. Leave it on the stock size tires. It'll tow just fine how it is. It will be slow doing but it will do it.
Now if you want to stay 6.2 powered and have it run better, I can give you a long list of things to do that'll make it run really good.
Feel free to send me that list if you like! I recently picked up an 82 C20 single cab dually that apparently was a cab swap on an 84-85? engine and chassis.
Sub'd to watch the progress and learn.

Nothing to apologize for Ethan. the big difference between the 700R-4 in 3rd gear vs the SM 465 in 4th isn't the 80 rpm...it's the torque convertor. Lean into the throttle a little and the 700's convertor unlocks and you pick up another 200 rpm plus some needed 'slip'. Do the same with the 465 and the result is very different. I get what you're saying, and I understand you love the 6.2, and I'm not that different minded. It's just that almost anyone towing an offroad K5 is going to be towing it to the parts of the country that are decidedly not flat. Anyways, I am certain we have beaten this horse to a complete pulp by now. Cheers!
Got her runnin!! Found one side of glow plugs not getting power thanks to the rats and the feed for the injection pump was ate off too. So some hose, a few hours and a but connector and it started.
Hard to tell but I pulled a 30 gallon trash can full of rat shit out of this truck.. Unbelievably disgusting. And there is still more in it.
Glad I could help pull it out of the depths of purgatory. Can't wait to get working on this one. But we do have 2 trucks to finish, 1 scheduled, then maybe we can play with that...
I couldn't play the vid?
Jealous of your j code intake

Aw bummer I'll have to upload it to YouTube.
And @secutright I just had to know if it ran, I agree though minimal effort on this until the others are done.

That's pretty cool that it fired up and it sounds good in the video.
I can smell rat piss though
