I’m not using a stock computer in this video. You would have to build a tune to run E85 since this setup is unable to determine if I am running E85 or another other specific octane. The OEM computer has a sensor to know how much ethinyl is running through the system and changes the tune to accommodate that.
I love watching first starts. This was great because nothing was done to it and I'm sure its more than enough power for my rat 53 chevy. Time for out with the old(weak 350) in with the new( newish)
Exactly what I did but I ended up granading that engine lol. It dropped a valve on the way to work one day. It was plenty of engine for my 56 Chevy truck though. Loved it while it ran.
My new to me, '04, Z71, Burb, 5.3 with 187K will probably need replacing. My mechanic replaced the oil tube O-Ring and all the lifters rattle like crazy. He says it's a flex fuel, L59, #Z and says his knows of a junk yard that may have two 5.3 as good runners which I would probably rebuild first. Love my Burb but just can't trust it far from home rattling like that. Any Sugestions? Thanks for the video.
You don’t have to use a L59 to replace it since the engine is the same as the LM7, the fuel injectors are the difference and the fuel system from the factory truck. If your not running E85 the fuel system doesn’t matter, but the flex fuel injectors are bigger so that’s good for tuning. I’d replace it with a good running cathedral port 5.3.
@@sharpie132 I haven’t tested it in anyway so I don’t know for sure but I’d assume the thicker wire has less resistance. I just like the way they look and I’ve always ran 8mm - 8.5mm wires on all my engines.
At 0:41 the bog down to almost the engine dying is normal for these engines correct? Isn’t that the computer re-adjusting the air/fuel ratio after a high rev? Because my Flex Fuel L59 does this and mine is on the factory GM tune.
@@GreymancustomzI have one fully functional and running in the vehicle itself and it does the same thing at 0:41 when it’s running and everything is working when the vehicle is running. Maybe something was missed in the tune when my L59 was swapped into the vehicle.
This engine is running on a Holley terminator X max so there is no security to bypass. But for OEM computers you will need to buy the HP tuners adapter and download their program to access the computer and modify the security settings. I have an OEM computer on my 2wd 1956 Chevy truck
I got my hands on the 07 avalanche 4 x 4 and I’m gonna be putting everything in a 2001 dodge ram that I have going to lift and I put a Chevy 4x4 solid axel on the front
The terminator x max by Holley doesn’t use a MAF. It’s running lean because the computer is learning the engine. It’s a run stand so I don’t run the engines more then a hour.
That engine went into my truck and I ended up blowing it up somehow, stay tuned for the tear down videos to come about that. Check out my new videos about the L96 that’s going in the truck next
Having a content creator that responds to all of his viewers says a lot.
I try but sometimes I don’t get to them for awhile.
For those who watch this video, I have ran straight E85 through my L59 with the factory tune and it didn’t explode or throw a rod.

This is the CLEANEST AND NICEST first start I ever seen in my whole life .
The run stand makes it easy
You didnt see the first start, what video are you watching?
@Avalanche2 hummm ok pothead 🤔 I thought this video is the first start just like it's says on the video title 😳
@@EARTHKEENING LOL, OK meth head. We can pretend.
This is awesome
I enjoy doing it

Exelente.super.engine
It was a great engine. But I’m now putting a 6.0 in my truck
Nice!!!
Thanks!
Love it
Thank you
Could you share how you made that engine stand and all the instruments you used to make it all come together
Once it’s done I plan to do something like that
@@Greymancustomz ok I’ll be on the lookout thanks
+1 for the engine stand
Same!

Sounds good, what spark plug cables are you using there?
Those are MSD wires.
@Adam Parker does it make a difference from ac delcos

I run the msd,s on both of my 6.0's one in a 2005 2500hd one in a 2013 2500hd. They do really good.
What was up with the flex plate? Looked like it was wobbling?!
I bent it when I pulled it out of the donor. I replaced it before it went into my truck.

It won’t start learning till the engine temp hits 160 degrees. The fuel map may have been set up from the prior engine that was on the stand also

what size injectors comes with the 99-06 L59s? i’ve got an 03 L59 in my single cab just can’t seem to find the right information about it
I don’t remember exactly but I believe they are 30lbs injectors.
36lb depending on the year
03 has 33.6 and 06 has 36
@@Thattb999 technically it’s all 36. 03 rates it differently because of the return style rail
😢😅
Google on all cylinders
nice! are you using flex fuel in this video
I am not. I like getting the flex fuel intakes because of the bigger injectors
Do you remember the part number for that belt?
5060760
I don’t remember what it translated to though in gates.
How do you bypass the security for the ignition
This engine is running on a Holley terminator X max so there is no security to bypass. But for OEM computers you will need to buy the HP tuners adapter and download their program to access the computer and modify the security settings. I have an OEM computer on my 2wd 1956 Chevy truck

@@jaramiaponce8894 nice. Make sure you delete the DOD and the VVT functions. Maybe go in and change out the lifters and block off the oil ports.
Where you located I need you to come get my truck going
I’m in California
Your missing the MAF sensor on the intake is probably why your running lean and not running crisper throttle there
The terminator x max by Holley doesn’t use a MAF. It’s running lean because the computer is learning the engine. It’s a run stand so I don’t run the engines more then a hour.
Tf is your flywheel doing 😅
It’s bent from when I pulled it. Came out of a 4wd truck. First one I pulled from a 4wd
I hate you so much for posting this! The jealousy is oozing out of my nose and eyes!

@@GreymancustomzWow sorry to hear that. That baby was purring like a kitten. I'm dying to get a LS for my 85 blazer sitting under a tarp.
@@Greymancustomz did you find out what went wrong ? Did it overheated ?
This reminds me of my passed father , back in the 80’s make motors run on his motor stand 👍🏼👍🏼♥️
Nothing wrong with this engine. I ended up blowing it up later on but that was due to a mistake I made.
I call this BS I have never seen this clean in any upstate ny yard in 6 years
Hahaha I’m in Cali.
There is corrosion up North. How is that BS? This came from Cali apparently.
Yes I’m in Cali
