I can’t believe its over! What an amazing series. What am i gonna do what my Saturdays now?!
Watch our next engine building series! Thanks for watching!
Start your own build
Couldn’t have said it better! 😂
You’re really the goat for documenting this entire process from start to finish bro. Like fr fr this is so thorough, and will be super beneficial when I decide to rebuild my lm7 in my gmc pickup.
Thank you so much for watching!
If you are returning the engine back into the stock vehicle and still want the Ac compressor and powersteering pump etc, do you still need the alternator bracket, or something or else or keep the stock form?
Just get the stock bracket so the belt path is stock. Thanks for watching!
I really enjoy how each video is straight and to the point, filled with super important tips. I have watched these a few times! Thank You!
Great! Thank you!
Summit gave the parts to the right person! Thank you for this very detailed and professionally done video. Didnt leave anything out. Def will become a summit customer because of your video. I was very against summit at first because of them not having a tech department. Thanks again!
Glad it helped!
Ryan, Do you have a plan for this gem yet? Asking for a friend...
Hey Andrew, not at this time. I'm kinda leaning toward a 3rd gen Corvette. But that could honestly change at anytime. Thanks for watching!
Most under rated Chanel! Good stuff
I appreciate that! Thanks for watching Billy!
This was the best series of videos I've ever seen for rebuilding a motor thank you guys. When you Dyno the engine are you going to go over your fuel delivery the kind of pump you use etc
Thank you so much for watching Mike! They handle fuel delivery at the dyno. But I will go over as much as possible when we get there.
Wow. I cant wait to do this to mine, so much detail in the videos!
What size injectors did you use, Also what type of fuel rail did you use also
These videos have been so great! I am looking for an LM7 to do my own build now because your videos showed me it’s possible! I also started following your Big Block series. Love your videos!
Go for it, it is possible! Thank you so much for watching Edward!
Can I used that alternator bracket for the opposite side of the engine?
@2CarPros…thinking of upgrading to a metal intake manifold, mines all stock. Do I need to upgrade or Tune anything just after replacing with a metal manifold? That’s all I’m wanting to upgrade. Rest will stay stock.
No you don't. But changing out the intake won't do much for you over the stock unit besides looks. Thanks for watching!
I've been looking into rebuilding my 5.3 for a few months now. I looked up some rebuild videos today and have watched the entire series in one sitting. The detail in this series gives me confidence to do it myself with a little help from a mechanic friend. Beautiful build by the way!
You got this! Let me know how it goes! Thanks for watching!
What injectors did you use on this application
"Be ginger" LOL
And gentle! Thanks for watching!
I just want to say thanks for all the videos, Help Alot on my build Sir!!!
I'm currently doing the same build, I have 2003 Lm7 5.3 bored.020 with LSA supercharger to put on top. Going into 1984 chevy caprice, using I.C.T billet adapter plates, and energy suspension motor mounts.
My question is which steam line ports would be the best .
Block the back 2 off and just use the front 2 or use 4 steam port that loops around super charger to the frt.
Just thought I asked since I'm using a super charger,
Thanks Again For All The Help!!!
Awesome! Love to read that!
4 is always better than 2. It has to do with how the engine is tilted in the car. So it's just easier to go with 4 and avoid any kind of air bubble in the heads.
Thanks for watching!
@@2carpros
Thanks for the reply info and you're advice.
Also I'm enjoying watching the build on that ShoeBox Chevy!!
So can I just run the stock steam lines? Also can I dead head the rail on one side and will the fuel pressure be fine? I shouldn’t have to use a aftermarket fuel pressure regulator right? I have this intake but for some reason the connecting of the fuel lines to the rails is just confusing the crap out of me. Thanks.
Hi watch this series I cannot count how many times I have been doing my build off of all your videos well yesterday I put my heads on and realized I did not put the lifters in so I took the heads back off and reinstalled the lifters and then used the same fell pro head boats to fasten the heads back on I did the OEM procedure and they felt like they had a nice clamping force what do you think should I go with it or should I teared apart again and get new head boats
Ryan, maybe I missed it, what MAP sensor fits this intake? Thanks
I believe this is your guy www.summitracing.com/parts/ado-19418808?seid=srese1&gclid=CjwKCAiApfeQBhAUEiwA7K_UH3M55ZFFktg4szIiZZ_GKtG0aYAigJeZ-xeyQZ8Cn3OQnjUiILFl6hoCQCwQAvD_BwE
But you might want to call Summit's tech line to confirm, they are super good. Thanks for watching!
I’m doing a lm7 5.3 build as well with a single turbo kit, I’m only going to use the front steam crossover tube, question is can i block off the water pump spacer hole & use the accessory drive like yours?
Nice! Sounds cool! Yeah I can't see why you couldn't do that. I would be concerned the steam lines not working correctly without it though. Thanks for watching!
@@2carpros well i just bought it & I don’t want to spend extra money just to get the kit that you bought so i can get everything to work properly
Can you please send me all the part numbers so I can order the same parts Thanks
They are all here on Summit www.summitracing.com/newsandevents/newproductreleases/2carpros-5-3l-gm-ls-engine-build-parts-combos-now-available-at-summit-racing Thanks for watching!
I just think the factory 4 place steam pipe looks cleaner
Whatever floats your boat as I always say! Thanks for watching!
Can't wait for the Dyno.
Same! Thanks for watching Shawn!
Is that ls 5.3 for sale
What is the total cost of these builds, can you add that into your videos
It fluctuates. It’s more expensive now than when I did it then. People would be upset if I told them 6 and then it ended up being 7 or 8 due to inflation. Thanks for watching!
Can you show how to make a strip-down version of the harness
I don't have a harness at all, so I will most likely have to go with an aftermarket solution. Thanks for watching!
I was looking at the summit oil pan but I noticed you cannot screw your transmission to the pan like the stock what do you do in the situation do you just not screw the bell housing to the oil pan
Correct. Just use the engine. Thanks for watching!
@@2carpros is that Safe I really wanted to go with that pan I love the fact that it’s metal and painted I ordered one aluminum Harley clone on eBay and it came damaged I just ordered a different one from eBay hoping it works but I would prefer to go with this one just didn’t know if it was safe to run it with the all the housing bolts bolted
Nice video!
Thanks!
Super interested to see the dyno results
You and me both!
Can you tell me which injectors you used
Check this video out th-cam.com/video/_38N4_dem8A/w-d-xo.html Thanks for watching!
Evan shanks?
What was the total cost all said and done from picking the engine up to break in and dyno?
I think the engine was like 7 and the dyno with LS tune was 1200. Thanks for watching!
@@2carpros you're awesome. Great content. And thanks for responding. I realize I'm way late to the Vidz. Love your stuff. And thank you.
Mil gracias por tus videos me ayudaron mucho en mi proyecto salufos
Do u have the part numbers to the steam kit where it T’s out to the water pump spacer?
Yeah it's in the steam line kit. But it's just a -4AN ORB junction block with 1/8" NPT port and one -4AN to 1/8" NPT flare adapter. Thanks for watching!
@@2carpros would I have to buy more plumbing or tubing for the rest of the way down to the water pump spacer?
Great videos man. Question to set the timing you move the crank to cylinder 1 and make sure it’s at tdc then you slide the lower sprocket on and that all you have to do?
Yep! Thanks for watching!
All that work for a low hp engine.
Since when is 500 with accessories on low? I guess if you compare it to a hellcat or something crazy like that but this is for everyone to build. Seems like a decent amount to me. Very street-able and reliable combo. Thanks for watching!
Great series! I'm almost sad it's ending. If you're looking to donate that baby, I have an '82 S-10 in need of a motor..
Thanks so much for watching! We will be doing another engine though!
I’m getting an lm7 this week and I’m curious what size bolts you used to attach the cradle to the heads? Thanks
You can use header bolts in the header locations if you thread them in far. I don't remember the exact bolts for the front and rear of the heads though they are a bit bigger than header bolts I just head laying around from the tear down. Thanks for watching!
I just found this series again, watched back at the beginning. I will be following this for my build and cloning what you do. Please get it on the Dyno ASAP!!! I need to know how badass my new engine is gonna be
That is so awesome! Thanks for watching! It's at the dyno right this moment. Should have the numbers by the end of the week and the video done by the next.
Not sure if anyone asked yet, but whats the total cost of all the aftermarket parts thats been put in it?
Also loved the series, very detailed and simply explained. Keep it up.
I have no idea honestly. You could add up everything we used. But you don't have to get everything new like we did. Like if your rods were in good shape that would save you 500 bucks.
Thanks for watching Avery!
Great job on all these videos. Gonna take a shot at this now. So did you drop it in anything and is there a video for it?
Great question! We started swapping it in our 1955 Bel Air, here is the first video on that! th-cam.com/video/V6yIwInSHvA/w-d-xo.html Thanks so much for watching!
Great video series.
Glad you like them!
Whens the dyno video coming?
Hi, Ryan-
Do you have the part number for the water pump bracket from ICT with the steam line port? Summit has several thicknesses available in their website. I am using the same water pump and need the same bracket.
Nevermind, found it! Thanks!
Nice work! It came with the kit I used so I'd just order that one. Also ICT has the best customer service so don't be afraid to reach out to them too. Thanks for watching!
Thanks for taking your time and recording this series and then taking the time to upload to your channel. Also thanks for adding all the links for parts in the description section. Just out of morbid curiosity I have wanted to rebuild an engine for a while now. Just to do it. I'll either sell it when I have completed it or find a vehicle to swap it into. Block I am rebuilding is an LC9, which is a 5.3L gen. 4 aluminum block. Probably go with forged pistons and rods. The stock crank should suffice for the power level I am looking at. If the crank needs to be turned, then I will probably just buy a new stock one. I'll need to run to the boneyard one of these days and pick up a set of heads. Last time I was there I had a chance to grab a set of 706 heads, but was a little too lazy. The beauty of this is I am doing it for the learning experience and I have no time table so I won't be rushed and I can take all the time I need.
That's so cool! Ever think about putting it on the dyno just to see how much power it makes? Thanks for watching!
@@2carpros Yes. That will probably happen, because if I want to sell the person buying it is going to want to know what kind of power it is making and make sure that during the initial start up the engine runs great. No oil and aluminum milkshake and rings get seated, etc. I have a 1986 Grand National I could swap it into, but the rebuilt stock motor in it only has 3k miles on it and most of those are just cruising miles. I have only went WOT with it once or twice. Believe it or not I have not taken the time to properly tune it. Not much to tuning it, just adjusting the methanol injection. With an optimal tune it will probably make 550whp and a similar torque number. Swapping the LS into it, will allow me to save the stock rebuild which was about $17k. I'd have more power to play with and not really have to worry about hurting the motor as the LS is so much stronger. Thank you
Man the things I'd do to be lucky enough for Summit to send me build parts like that for videos! These have by far been the BEST and most detailed LS build videos ive seen! Awesome job!
I am super fortunate to be sponsored by such an amazing company. I count my blessings everyday. Thank you so much for your kind words and for watching! :)
@@2carpros I'm sure there's a lot of requirements to meet to get sponsored, but thats awesome!
Can you do a how much it cost video so I can follow your videos haha
We won't be doing a video just on that but Summit is building us a page with everything on it and I will be posting it was it is done. Thanks for watching!
I really have enjoyed this entire series!! Really well done!
Yay, thank you!
Can I use these same parts for my L59 engine?
Yeah there is a lot of cross over. Thanks for watching!
I have a 2003 lm7 out of my trailblazer that has knock/slap not sure but it still runs good, I’d like to rebuild it but I’ve never rebuilt an engine. Do you think an ls is easy enough for a novice to rebuild?
Yeah definitely. It is the easiest automobile engine I have ever built. The easiest was a 1 cylinder lawn mower engine. Thanks for watching!
@@2carpros do I have to send the block and all to the machine shop? I’m just not sure what size bearings you’d need for everything and stuff like that.
@@dylanrhode4361 Check this video out th-cam.com/video/RvBYxpRC464/w-d-xo.html
Can I use twin turbos on same build and same parts that you used from summit what do think about dyno numbers ??
Yes if you get a forged crank. The rest is turbo ready. You might want a different cam and valve springs though. Thanks for watching!
What’s is the expected numbers on wheel
Ready to build one and put in my 96 tahoe
Nice! Thanks for watching Josh!
Can't wait to see the dyno numbers
Same! Thanks for watching!
did you use a stock accessory belt?
No, it is quite a bit shorter. Thanks for watching!
total price of the items whil kill your creditcard
Well you don't have to buy everything I had. There are some serious ways to save some bucks. Thanks for watching!
Price out a professional (400ish horsepower engine build) and compare... lots of ways to save money on this build if desired. Ryan did it 100%. Not everyone will choose the same. To each their own.
Lame it's over!!
I know! But we will be doing another engine. Thanks for watching Mike!
::single rolling tear::
::in slow motion::
Don't worry, we will be doing another engine after this!
@@2carpros any particular one in mind?
Been thinking about my buddies 302 in his 1981 Bronco that needs a rebuild. Thanks for watching!
Seems that I need new buddies I think...
This makes me want to go out and rebuild my 250K mile 5.3 even though it’s not quite wore out yet. I’ve fed it a steady diet of Amsoil all its life so it still has a lot of life left.
You keep taking care of it, it won't need a rebuild for a long time! These LS's are incredible. Thank you so much for watching!
Hey, Was the new summit racing harmonic balancer used in this video The same height as a stock LS harmonic balancer? I only ask because I don't want to have to change out my other accessories/ having to get spacers for truck style LS water pump
I want to say yes it was because we used the truck style water pump and it lined up. Thanks for watching!
Absolutely never use a hacksaw… high speed cut off wheels leave no burrs and easily seat into the fittings, always done it that way like everybody else for 20+ years and NOBODY EVER used a hacksaw but i guess i didn’t have some cutters i was trying to sell.
I use what works and a hacksaw did. Thanks for watching!
@@2carpros not well, cut-off wheel doesn’t leave the wires sticking out but keep selling those cutters!
@@jeremysmith6905 Worked fine for me. I don't sell anything or any financial kickbacks. Also most people don't have highspeed cut off wheel that they would have to buy since you have some sort of problem with buying things. Most people have a hacksaw ironically.
