Peterbilt 379 flat top lowboy project

After searching for quite some time I found what I was looking for about a year ago.

1998 Peterbilt 379 exhd with a 3406E 10 speed. Non ultra cab unibilt.

Started as 63" unibilt on a 252" WB.

Now it has been shortened about 32" and has a 2013 36" flat top sleeper.

I am also on my second and final lowboy trailer.

Pictures are from the day I bought it last summer down in south Georgia. Already had straight pipes and it sounded amazing. I couldn't find a long hood with the big Cat in black so I drove it straight to the paint shop.

The truck had not been polished or waxed in several years. Lot's of work ahead at this point.

I went with aluminum fenders to replace the originals.

Been awhile since I posted here. This project has grown into a full restoration modification project.

The wheelbase was shortened to 220" from 252". Removed the 63" sleeper and went with a 2013 36" sleeper. Also went through hell to get a door window, a side window and a rear window.

Yes I did have a couple vids up on youtube but took the channel down. I have another channel started but have been really busy digging everyday and can't find time to edit videos plus the Peterbilt is still undergoing severe surgery. I'll definitely do vids of the Pete when it's done though. I sure miss driving it and the sound was incredible! I don't know exactly why it sounded so good but it was amazing sounding the second I got in it after buying it. The blow off was amazing and would bounce off of buildings and concrete medians like nothing I've ever heard. The whistle was super strong too. I think all that's history with the new power plans though. It's too bad.

Love the Takeuchi. I used it a lot and it's really treated me good.

Absolutely and thanks!

The paint and body is finally done and it looks incredible. After being at the third shop it was finally done right and that was a total of 13 months away at those shops. It hasn't moved a 1/4 mile in over a year except behind a tow truck between shops. Now it's home in a dedicated garage built just for the re assembly of everything. The paint looks amazing and was done by Vance Wheeler at Peachstate Freightliner. It took 3x's as long as I was told and they didn't turn key it like I was promised but the main thing was the paint. He used top of the line clear coat base coat and there is not a flaw on the entire job. Vance the painter made a personal promise to me to do his best work to date and he did. The shop managers were trying to rush him and he ignored them and sent me pics daily. I was screwed twice by the other shops and he was dead set on making it perfect for me. I owe him big. He has received some trophies and one being 1st at World of Wheels on a 379. He should open his own shop because I was referred to him by the guy who got the trophy and people come from far for his work but he is limited because of the mass production a shop that size must produce. He worked Saturdays and Sundays off the clock till his hands were bleeding. He is the saving grace of this project. Vance Wheeler..... pretty cool name too.

As soon as he finished his part I had it towed home to the garage I built for it. Roll up door, carpet, heat and all. Now it is overwhelming and I need motivation. My work has me swamped and leaves me little drive to do all the work.

The side sleeper window was installed along with the sleeper door window, both doors were re skinned, hood emblems removed, roof shaved, fiberglass double hump rear fenders painted ready to mount, frame holes filled, under coating on bottom of sleeper, entire frame and suspension painted gloss black, new aluminum front fenders, new polished aluminum fender steps from Peterbilt

At this point I have these brand new parts or mods.

Replaced front axle with "car hauler axle" E1202W
12 gauge Gen 3 front air ride with dual gauges and switches for rear bags also
12 gauge strapless air cleaner mounts
New 15" air cleaners
Built by Bub mirror frames painted black to match
Outlaw Customs single window conversion motorized L&R
Moto Mirror kit includes both L&R mirrors 4 way and heated
Midwest Stainless visor
New battery boxes for L&R cut and polished by me
18" smooth side step boxes with matching 18" in frame tool box polished
Truk Guts full interior with 36" full sleeper panels to the floor
Texas front bumper with four light cut outs
New set of enhanced Alcoa's 24.5
New aluminum complete grille surround
Details billet vertical grille
Blue hood springs and cables
Hood latches

Engine so far: These are all new parts with the exception of the transmission being a rebuilt unit and the flywheel resurfaced

Rebuilt RTLO20918 18 speed with yoke
Resurfaced flywheel
Eaton 2050 tq. clutch
Shift knob with lines and 18 speed pattern decal
Rear seal
5 Core Radiator
A/C condensor
Engine Fan
Belts
Horton fan clutch rebuild kit
PDI Harmonic balancer
PDI Extruded, honed, and coated exhaust manifold
8" complete exhaust from the turbo back with 8" "Y" Lincoln miter cut
High output Delco alternator
Wiper fluid tank and pump

I have gone all out on this restoration modification project.

Still need the four black leather air ride seats and a set of 10 lo pro tires.

I am also going to go with a cam and injectors. I just need to lock down which ones. I might even go with a compound turbo kit from PDI. I just need to talk to the man. I sent my ECM off to get re flashed to 600HP 2050TQ and pre files and whatever else he did. He is a member here.

I forgot how to post pictures here. I think I have to upload to Flickr first unless anybody knows a quicker way. I will try tomorrow.

Well I have since learned that a 6TS will not support the 900 HP to 1000HP I am looking to get.

I have been doing a lot of work and research on this 2 year project. I've talked with Robsredford several times. I've been talking to Mr. Haney recently and he like everyone else says I'm taking a risk pushing a 6TS to 1000Hp. I've concluded that even 800Hp or 850hp on the 6TS is a gamble. I have the PDI manifold. Those guys loaded a 600 file. I have the 1000 Hp Cat marine cam and I have a new set of 58 injectors on the way from cat.

I've gone all out on this project. I just haven't posted the updates up to it's current stage. There is a great used yard to deal with here. They treated me real well when I just recently bought a rebuilt RTLO20918 18 speed from them

My question is this. They have a couple 6NZ engines and one 5DS 15.8 liter. Price is the same. They have a decent guarantee on the sale. I might rebuild before installing but of course don't want to. Which engine would best for my goals? Instead of building the 6TS up I would rather get a stronger engine and like the 15.8 liter and of course the 6NZ is a winner. Just need some advice. I don't want to call those guys up again and drag them out with my plans. Writing it on a forum gives a person time to think and reply at their convenience.

So 15.8L 5DS 40 pin or 6NZ 14.6L? is one better than the other? Stronger block?

Some pics from along the way. Replaced the door skins. Replaced the axle with a 1202W for better turning and more drop. I like the looks of the wider axle in the front fenders mainly.
