500Hp ,401, update, test drives, tuning begins!

I've had my share of problems. Oil line Fire, the worsr(all burnt wiring repaired except fuel gauge wires),727, pan leaks,(mopar gasket fixed),belt alignment(pressed WP threaded flange fix),stock air cleaner to Holley DP HO 750 carb(1/2in adpt fix), dialing in the big cam and carb to work with the mild(1800 stall, 2100rpm flash converter), carb benn off 20 times for changes, it finally got time for some short test rides!
Drove several 4-5 mile slow(3500rpm max) test, returned for adjustments. My 10 year old son(I'm 62), loves off road, was with me yesterday, and on several other test. Almost home he said, it just don't run like it did when it was in the car dad. Now it's still choked down with only 2in cherry bomb style pipes, and the single valve springs still on(I have triples to install,4500 max untill), we left the last stop sign turning right,1/4 mile from home, I laid into it hard, Lit the rear tires up for just couple seconds, tact hit 5k before I could get out of it, he grinned ear to ear,said now that's what I benn missing.
Springs going in soon, then going to muffler shop to uncork, I think I'll be happy.


500hp, 401, j10, update- test drives

It's those small, amazing moments that erases most of the misery.

Sometimes I seriously question why I still tinker with cars...and then that moment happens...and I forget the question.

Congrats

I'm changing the valve springs now! Broke it in with singles, adding the inner now,got 14 out of 16 done, the 2 next to the heater box are a Job! Gotta disassemble the spring compressor to get it on the stud, then re assemble.
I bought from summit a really nice tool! I had 1 of the old flat bar kind that took 3-4 hands to change the locks and springs. This thing screws on stud, compresses spring, holds itself compressed, while u remove locks, then u open it, remove spring and seal, add inner spring and new seal, then lock it back down, grease locks, place on stem, and release. Much better than the old flat bar I had!
I'll be able to turn it up, without worry, after I finish springs! My son has a u-tube channel, I'll post viedo on when finished. It's going to Fry those stock sized 235/70/15s!
I'll be looking for a posi carrier for my D44!
Anyone got a good rebuildable used 1 for 3.55s???

Is this the correct 1?

https://www.justdifferentials.com/AG...5420110-hp.htm

Wanna sell? Is it good shape, need rebuilt? Fit 3.55s?

I didn't realize new 1s were so cheap (if that's the right 1)?

Thanks

Ps-and what bout this 1? Is it better?,stronger? Why cost$more?

Recomandations!

And what bout this 1?

https://www.justdifferentials.com/PL...pld44-3-30.htm

The 2nd one is a Power Lock and is considered to be one of the best/durable LS out there. The Auburn is a Light Duty LS that will likely wear the clutches sooner than the PL. However, the PL cost almost puts you into the Detroit TrueTrac which uses gears and doesnt wear out. https://www.ebay.com/itm/Eaton-913A5...sAAOSw8WJfXbaf

Thanks, but too much$. I'll go with one of the first 2. I'm using this thing as a daily driver, farm use truck. I'm not beating on it off road(I have a 70cj5 for that).
2-
Test after spring install!
I put a 5400 pill in the shift light, son and I headed to county line and back(1/2mile straight).
Turned around at crossroads, an hammered it, away we go, starts pulling HARD bout 2500,
Took it to 5000, shifted to 2nd, nice little chirp of tires,took it to 90mph, hit 3rd and let out.
Slowed to 60mph,hammered it again, snap, lost throttle, coasted to nearest pull off.
Cable poped off ball stud on Holley, replaced and drove home.
More fine tuning to carb, small hesitation when accelerating from cruise to speed up.
Pulls better off idle than I expected, but it don't explode @3000rpm like it used too.
Think it's the choked down 2in exhaust!

What year is your truck again? My 79 Cherk has an orange lead from the sender to the frame rail. There on the frame rail, there is a spade connector that connects it to a pink wire. That pink wire is part of the chassis harness, goes up the frame, up the fire wall, connects to the big bulkhead connector, then Pink into the dash up to the round connector on the back of the cluster.

A note on exhaust... if you are going to keep 4WD, it can get really tight down there trying to fit a pair of pipes (2.5" or 3"). Especially on a QT/TH400 rig with a low range unit. I see you have a 727 so hopefully it is easier for you but if you are running a 727 right now, without a Xfer case, and you plan to add a transfer case, you should wait until the 4WD is complete before you pay for a new exhaust or you might be doing exhaust twice.

That's exactly what I needed, orange to pink,I followed the wire but the color at top didn't match. The oil fire was on the pas side, melted the wires coming up from t-case.
I repaired them, everything else works, don't see how they affected fuel gauge?
Their is a brown,and tan wire fron t-case plug, going nowhere?
My pink wire is connected in bulkhead. Right below theirs a 5-6 wire plug, bout 10in,
The pink goes through. The wire beside the pink has Fried the cover off, and melted itself to both sides of adj wires. I'm going to start at plug and test.
Should I get volts on the pink, or ohms ? Key on,or off?
And yes I have a t-case and low range, staying on! I think 2.5 will go above crossmember? 3in would have to go below.

I assume you have an 82 so I am not totally confident its the same as mine.

Take it one circuit at a time. So, when you go key on you should get 5V on the pink wire. That same 5V goes to your temp sender and your oil pressure sender. So if those gauges do not work, you have other issues. If those gauges do work, and you get 5V to your bulkhead, just follow that down to the tank. Make sure your tank is well grounded, too.

Stock oil,and temp work.
So their should be 5v on the pink leaving firewall?
All the way to sender in tank?
I've already looked(felt) tank, both wires hooked.
I'll double check my ground.
Thanks.
Its really annoying, with no fuel gauge!
I put a couple gal in ea time I go to store.
PS- my fuel fill is Really slow?
Pukes gas back up the fill hole.
I replaced both hose to tank with correct bend new ones.
No change?

No power on pink wire under hood.
So pull gauge panel and check for 5v?
Where does the 5v come from that feeds the pink?
I believe u said that if the temp,and oil worked, panel was hot?
Ps-I I've benn running it a lot in shop on Jack stands making adjustments,
Last night I took to local store for road test, started running out of fuel
Bout 1/4 mile from store, kinda pated pedal and coasted to pumps.
This engine got around 14mpg in car, closer to 10 now.
I've since added a 2gal fuel can to my bed!

Yep! 5V is created inside the temp gauge. Called the CVR (I don't remember what CVR stands for). You can see it here (pretend the red line does not exist on this picture):


There is a round wiring connector on the back of your gauge panel and that 5V leaves the panel and heads to the bulkhead connector, through the firewall and down the chassis harness. The pins on the gauge panel can come loose. You may have to solder it back on. There is a really good write up in the service manual for fixing gauges. If you go to this link you can probably find yours for free download:
https://oljeep.com/

Yeah, I think we all get about 10'ish. Your J20 is a big heavy brick compared to your car. Probably at least 1000#s heavier and almost as aerodynamic as a barn.

Guess I'll pull the panel next and try to find 5v?
I just had it out month ago, reglueing the lens,and cleaning.
Might have left it loose?
Yes my car weighed bout 3000lbs, according to the web, this thing is 4400lbs?
It will rarely be more than 15miles from home.
The mpg should be offset by fun per gal!
