76 Blazer LS swap
 

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.

Re: 76 Blazer LS swap
 

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!

Re: 76 Blazer LS swap
 

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?

Re: 76 Blazer LS swap
 

yes it will have the factory air with a low mount Holley compressor set up
I will run DBW, I will post pics of the pedal soon
the engine/trans will be controlled by a Holley Terminator EFI system
in-tank 255lph pump with a corvette regulator/filter

Re: 76 Blazer LS swap
 

looking forward to see how that low mount works out!

Trans cooler mounted along with the A/C condenser, Earls Ultra-Pro oil cooler

Fuel system build using a Holley 12-914 fuel pump on the factory blazer EFI tank

Re: 76 Blazer LS swap
 

Nice truck

Re: 76 Blazer LS swap
 

Holley EFI going in, Holley will be controlling the LS3 engine and 4L75 trans. made a bracket to mount the GM DBW pedal along with a MSD solid state relay for powering the Dakota Digital dash and Holley ECU

Looks sweet! Nice and clean..

Re: 76 Blazer LS swap
 

Clean build as always, :metal:.

Re: 76 Blazer LS swap
 

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

Re: 76 Blazer LS swap
 

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!

Re: 76 Blazer LS swap
 

Love it, thanks for the swap tips!

Re: 76 Blazer LS swap
 

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

Re: 76 Blazer LS swap
 

beautiful ride! love how clean you made the install. I have been thinking my Jimmy might need the LS treatment.

Re: 76 Blazer LS swap
 

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

Re: 76 Blazer LS swap
 

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.
