the BIG BLOCK KILLER 4.8 is DONE! + electric fans on a 99-02 Silverado the RIGHT WAY
Автокөліктер мен көлік құралдары
After about a month of working on this stepside GMT800 Silverado, the engine is back in, its running, and after today, it'll be ready for tuning. In this episode, I add 2005 and newer silverado electric fans while keeping the AC operational just like the factory intended. This requires an additional sensor to let the computer know what the AC pressure is, so it can control the electric fans when the AC is engaged. The 4.8 LR4 in the stepside features a 220/224 cam, a new oil pump, Comp 918 beehive springs, LS7 lifters, BTR trunnion upgrade, all new gaskets, ARP head bolts, gapped rings, and a whole lot more. The goal to compare against is the 300whp Gen VII big block, and while I'm not positive we will make as much horsepower as the Uglytruck, I think the 4.8 has a fighting chance.

Finally an electric fan upgrade done right 🤟
As someone who is in the infancy stages of tuning, could you elaborate more on your tuning process? Keep up the good work!
Awesome job LT! Thank you for taking the time to show us the correct way to do it.
Enjoying the build. Can’t wait for the first test drive.
Absolutely love the stock appearance of this build!!
Dude, I really enjoy how well you walk us through the project. I’m hooked on watching all the cool projects you get your hands dirty with. Keep up the great work.
Love that you go with stock cooling and hp tuners. Very helpful.
Thanks, this is what I have been looking for for my electric fans to work as they should.
Very impressive attention to detail. Love the way it looks so stock. Thanks for sharing your work
I really enjoy watching you do these upgrades...especially with stock exterior pieces(cooling fan, etc)...makes for such a clean & tidy install!😎
Another good one LT, they must miss you from your previous job. You do a great job explaining in detail and you also do very good work.
Watching the progression of your projects is great. Keep it up.

Thank you for explaining the pin 33 position.
Absolutely LOVE the clean OEM look under the hood. She’s gonna ROAR with boost!! My guess for HP on this one naturally aspirated is 265ish.
Can't wait to see the dyno stats. Nice work LT.
Nice work. Love the Sublime nod.
Can you do a detailed video for the ac pressure switch and it's wiring for the electric fan conversion
I like the stock look as well LT I love the feedback when you are explaining your process keep it up DR.Truck
Finally a proper explanation and info on efan swap without a third relay poorly added!
Man I love how this OEM+ approach, it's just very entertaining to see how factory parts are backward compatible.. I came from VAG and BMW background, and I do this a lot too. Currently running a factory M235I intercooler on a 220D.. same idea, super cheap parts, better cooling, factory fitment.
Nothing like a clean stock looking engine bay while having something savage lurking within I love it!
Good stuff LT u are one smart dude I just got my 05 extended cab in the shop 2 days ago starting on doing a complete new braking system w dorman stainless steel hard line kit. I awalys love your educational videos you are very thorough
This 4.8 is going to run great and breathe too!! The air raid intake is a great choice and using it in conjunction with the stock airbox, I put this on my 2010 silverado 5.3L and this cleaned up th idle a lot!! It is still quiet until you step into the throttle then you will hear it!! This along with the exhaust that you built should be a great combination, can't wait to hear it and I really enjoy seeing your exhaust creations, they are a work of art and your channel is one that I look forward to seeing, it is awesome!! :)
Thanks for the video LT, I appreciate the clean factory looking engine bay. Thanks for the link to the a/c parts. GM spent 10s of millions to get these trucks right so using factory parts is a plus in my mind.
I love the clean factory look

Love that gm didn't change much under the hood over the years. I retrofitted 05 e fans onto my 93 k1500 single cab stepped and made the harness to have high and low just like oem! Only needed minor modifications
Great build, LT. My kind of clean, factory appearing engine bay! Awesome work!!! Regards, Lloyd in TX
Keep it up, this is getting good!
I have a 99 Silverado 5.3 2wd that I have been working on for the last few years. Your videos have helped me to understand how it all works, especially this video. My tune for fan 2 “High Speed” was incorrect. I made the tune change you instructed and BAM, working perfectly!!!👍 It’s guys like you that makes KZread one of the greatest inventions of my lifetime. Buying the Summit Racing gen1 LS 450 hp long block next year. If I decide to go turbo, I’m gonna base everything off what you’ve done. Thank You so very much for your generosity! Please keep up the fantastic work! Guys like myself are very grateful! Thank you 😎🇺🇸
Dude! You just resolved every issue I was having with my fan install on my 2000 Silverado! I have looked for this info until I was cross eyed! Thank you!!!
Can't wait to see the outcome! 4.8l build is what I'm planning for my 2004 4.8l 5 speed manual. 🤙🏽

Hi LT, The look of the factory electric fans is very clean. Seems like a great way to go, all the fitment engineering has already been done for you by GM. Thanks for the video! -mike
Love tge way this build is going can't wait to see how it stacks up against the 8.1
Love how your choice to go w/OEM stuff, makes everything look original. Keep it up bubba! Can hardly wait for the "SEND IT" video(s).
One more "mod" take the small hose going from radiator to the throttle body and bypass the throttle body. Intake Temps instantly lowered.

Appreciate you Sir 🇺🇸🦅
Glad to see the Airaid MIT!
The editing was great I enjoyed this video most yet
Awesome how to on the correct way to do the fans, most videos just tell you about the wire harness not actually show you what needs to be done...🔥🔥🔥
Need more youtubers like this and less “HEY GUYS WELCOME BACK TO THE VLOG!!!”
awesome job ....
Very clean install. My brother has a super clean 4.8 long bed I might have to buy off him now hahah
really like the factory look under the hood
Very cool can’t wait to see what it’ll do on the dyno, I’m building a 6.0l I have a cam , valve springs, a fuel pump , torque converter and a trailblazer ss intake and I’ve got a vortec super charger that’s on my 5.7 that will be going on the 6.0l . Going to be putting it in my 97 Chevrolet Tahoe 2 door
Love it, getting ready to get my parts for my e fan conversion on mine. Hard to find parts here in Denver! these trucks are super popular right now.
Great job LT can’t wait for Sundays video!
Just found your Channel tonight. Your projects are awesome. The way you carry yourself on camera is too notch. Look forward to seeing some more videos.
Best mod for a 4.8 is a gear set. Small cubes and tall tires make the 60e like a power glide. I have had a few 4.8s and they work great with 4.10s
Can't wait to see the LS on the dino
Man I love this channel! I wish the song covers were listed in the description, it drives me nuts trying to think of what that song is!
I got the same intake tube on my 04 Tahoe I did drill sum holes on the bottom of the factory air box n dropped in a K&N air filter n wow what a difference truck breaths alil better n sounds nice!!!

Hey if the base idle airflow isn’t cutting it with your tune. Flip the throttle set screw and drive it down for the first try. Reprogram TPS and it’ll make the base tune SO MUCH EASIER

Absolutely fantastic content LT!! I've done three of these upgrades and had to do extensive research because it is hard find the right information to do it correctly. You just summed it up in one short video and absolutely no one else has done that. I totally agree to use the factory harness and fans (and you even got the best one). Just change over the pin and upgrade the AC sensor. Everything just goes right in place like was always there. Way cheaper than aftermarket and a noticable difference when driving. I did pretty much the same settings as you (but I can't understand why the stock on/off temps so much higher). Thank you so much and hi from North Gorham. I can't wait for the tune video, that should be fantastic, you'll be at 100K and then some with great content like this! PS great explanation on the bigger and smaller radiator. Just just look at the bolt-holes... 👍

I had to add that i did go to the 145 amp alternator from the 105 that was stock. Just grabbed a new looking one for 20 bucks extra when I was at the junkyard on the last one. Not 100% sure if needed but hope it can't hurt. Better gas milage, more power and A/C is ice cold.

Oh man that increase in MAF demand for the AC is genius and now I'm going to get that done because currently whenever the ac kicks the power bogs and has to recover. I wish I had known! (I also did that fan conversion)

Looking forward to seeing the tuning and dyno results! Then after AWD conversion, it’s “what power adder?” Spooling a big turbo with a small engine is problematic, so I wonder if you could plumb a twin turbo setup to spool one, then add the second through repurposing a big wastegate. Kind of an X-pipe to the twins. The ultimate power will be limited to what the turbo compressor(s) can provide, so you’ll have to match the lb/min of the S480 if you want a chance to match the 547’s power with the 4.8. There have been some complicated OEM turbo setups-maybe you can do one better!
Also there is an awesome vent gauge pod for that truck on Etsy that I have in my Silverado that fits the AEM Gauges perfectly, I would be glad to share some of my build with you if you would be interested.
More incredible work and here is my comment for the KZread algorithm!

I would love to see the awd conversion video and also could you get a 2004-05 2wd ram 1500 with the 5.7 and do upgrades to it and do an awd conversion on it as well because I'm thinking about doing that to my project truck of the same year and configuration and options in a few years after I graduate from automotive trade school
One thing... I don't think the HIGH speed fan will work unless you put an A/C pressure sensor into the system. I have done several of the electric fan conversions and the ONLY way I have ever been able to get the HIGH speed fan to work is by installing the GM A/C pressure sensor-just like all the factory trucks with dual electric fans come with. Without that sensor, I don't think the computer will ever command the high speed fan to come on. If you turn the A/C on and you don't have the A/C pressure sensor the computer will not command high speed fan for moving more air across the a/c condensor... Just so you know.... Essentially you MUST either install the A/C pressure sensor, or you can set up the high speed fan to be triggered any time the compressor is running, or the A/C switch is turned on. The downside to running the fan manually triggered is that the fan will run at all times when the A/C is on.. Even when you are on the freeway at speeds high enough that you don't need them to be on... Wasting energy, burning more fuel... It's better-let's just say mandatory-to install the A/C pressure sensor.... Just do it the way GM did it and you can avoid a bunch of drama. Those pressure settings he was changing in the tune @ 13:10 make NO DIFFERENCE unless you have an A/C pressure sensor... which the truck he is working on did not come with the pressure sensor on it from the factory. Why he was jacking with the pressure settings I don't know...
Ended up ordering the a/c kit and was wondering what made you pick the egr for your pins? I was granted I can use the egr pins now. Just wondering since the instructions listed other pins. This video eliminated a lot of headache. Just a video alone of you doing that kit would bring move viewers.
holy shit ...epic...i been wanting to pimp out my 4.8 great build.!>
I just downloaded HP tuners for the first time to do this and I don't have any of the settings you showed other than the fan on/off temps.
Man you can get a cheap cai on amazon for $60, that’s what I did and noticed a difference in throttle response before I even got the tune
Did any one notice LT put that rusty old battery tray back in there, Haha, only kidding LT, live your work. I can't wait for Sundays video.
What about putting on dual piston rear calipers and rotors from a GM T800 Tahoe for better stopping? I’m thinking about doing it to my 2018 Silverado 1500.
My only question is, are you going to upgrade your alternator to handle the additional load from the fans? If so, ICT Billet has some great alternator conversion options to allow you to run the 160 amp DG44 from the GMT900 trucks… it’s the direction I went with my 99 extended cab…
Let’s go LT
Yoo Lt, quick question. What settings did you/do you adjust to get it to run happily with long tubes? I have hp tuners and am interested in turning off my 02 dummy light
How is the AC pressure switch working out? did you have to update operating systems?
My truck is basically the same as the ugly truck. The only difference is mine came with the 4.8. After watching all of these I’m definitely wanting to put more power into my truck
Warning Use high temperature exterior grade double stick tape always especially on the dashboard. You will really regret using anything but the good stuff after one afternoon in the sun. I used some stick on Velcro pads to hold a device to the dash once and the glue melted and made its way into every button and plug hole on the device and the dash.
