lukeembry · 01-25-2019, 10:35 AM

Just finished up a Blazer LS3/4L65E swap. thought I would share some pics of the build and maybe help others out if they are looking to do the same feel free to ask questions.

went ahead and installed a new heater core and evaporator so hopefully they don't have to be changed again. I will be using Hooker Blackheart swap headers and engine mounts on this build

Beautiful truck!

TooTall · 02-01-2019, 02:22 PM

Very nice headers
Are you going to run the A/C system?
How did you hook up the gas pedal? DBW or DBC ?
What are you doing for the engine harness?
Making your own fuel system in the tank?

Looks sweet! Nice and clean..

**Hart_Rod** · 04-25-2020, 09:26 AM

Clean build as always,

Ryan Hubbard · 05-04-2020, 07:19 PM

Which upper radiator hose did you use?
Who's radiator did you use?

I am doing this conversion on my Suburban and I like your setup.

Great job

swissarmychainsaw · 06-13-2020, 07:17 PM

And no one mentions the ridiculously clean garage? I'm jealous!

Do you have a part number for the trans cooler and mounts? Or is that the ail cooler sitting in front of the Condenser?

Is this a US Forest service truck?

I love what you are doing!

**LEEVON** · 06-19-2020, 04:25 PM

Love it, thanks for the swap tips!

Ditto (jealous) ...or the fact that the truck looks like it was wiped down with a container of baby wipes!...

!! well... I do believe that Luke is a top 3 builder on this site... next to "N2TRUX" and "CHROMAHOLIC".... just crazy detail and a scary eye for great build parts!!
thank you Luke for sharing & letting us observe your great work!!

zellway · 07-24-2020, 11:13 AM

I was gonna say, Truck, schnuck, look at that garage! But the truck is awesome too!

Mr.Rogers · 01-14-2021, 09:02 PM

Love the build! Which brand of upper and lower radiator hoses are you using and what are those part numbers? Also, did you do any engine work such as a camshaft or ported heads? How are you liking the power? Is there anything you would have done differently?

Apologies for all of the questions, I just thought I would get them all out in one shot.
