Project: 84' Blazer - LQ4/4L60e Swap

I'm sure many of you have seen my blazer on this forum.



It's a 1984 S10 Blazer (Tahoe) with a 2.8L/700r4 that has become very tired and is in need of an LSx Swap!

I will be purchasing a 2002 6.0L LQ4 and 4L60e from a auto wrecker in the next week or so. It comes with all front accessories, wiring harness, ECU, and plastic shrouds. Its already put to the side and awaiting pick up.

As of now this is what I plan to buy for the swap.

Parts list:
KWik - Alt and PS bracket
Kwik - A/C mount w/ sanden compressor
Stainless Works - 1-7/8 LT Headers
CPW - Radiator w/Fans, Shroud & A/C Condenser
CPW - A/C condenser and lines
CPW - Wiring Harness
Shift Works: Mechanical Speedometer Kit Tailhousing
Holley LS Valve Covers - Black
Holley - 302-1 GM LS Retro-fit Aluminum Oil Pan
Lokar - Midnight Series Shifter

I want to keep all factory gauges, which is why I have that tailhousing in my parts list. My main priority is to get the truck running and able to move under its own power by Xmas this year. Once that is done, I will work on the cosmetic touches, such as valve covers, tailhousing, lokar shifter, A/C, trans rebuild etc... As the engine has about 120,000miles I wouldn't be surprised if I rebuild down the road, but like I said, the main priority is to get it running.

I hope the Stainless Works headers fit without needing too much frame modification. Will I be the first one to try it???

Once I have the engine in I will deal with the fuel system. I'm sure I will have many questions to do with this...

So far I have only taken a bit of my front end off. I hope to have the 2.8L and everything else removed from the engine compartment by the end of the week.





I will be putting in an order with Jared at CPW tomorrow for the LT's, Rad kit, and A/C shit. I will also order the Holley pan and KWik PS and Alt bracket at the same time.

Stay tuned for progress!

Looks like a great plan. My advice is rebuild the engine now. You're not gonna want to pull it all back apart later to redo it all again like I did...
I'd love to, but I don't have enough money in my budget at this point. That will be down the road.

Can't wait to see how the headers fit. I have a first gen pickup I want to try them in. Do the early blazers have the perches on the frame for the motor mounts like the 2nd gen? Your blazer is clean and subtle, I like it.

Ill take some photos of the frame rails once I remove the engine so you can verify.

Nothing much new here, I've taken it quite slowly lately because I dont have any parts yet.

I will be paying for the engine and trans this weekend and it will be delivered early next week.

I've taken the whole front clip off and am ready to start unbolting the engine and trans as most of the wiring is out of the way.









More photos to follow as I make more progress.

The engine and trans are now in my possession!!! :)

I removed the front accessories and manifolds last night. Once I get some bolts, I will mount the engine to my engine stand and then continue removing my 2.8L.

I'll post some pictures later this evening.

How it was dropped off:






I'll be running a 4.8L flexplate to avoid matting problems with the 4L60e:



After tonight, this is how it sits:

Ready to pull the 2.8L



I got some bolts to mount the 6.0L to the stand









I removed the EGR components and I'm now looking for a block off plate as I will be running the LT's. Have any of you used this one ??



Should I remove the engine oil lines running from the rear of the pan? or should I keep them??

The new pan will have the correct plate over the oil cooler holes if you don't want to use it. I don't think cpw radiator has ports for them.

Goodbye 2.8L!!









Tomorrow I'm going to degrease the entire frame and firewall to get it ready for when it comes time to drop the 6.0L in.

I may try to mock the engine up with the DIY mounts from SD before all my parts come. The only problem is that I need the headers and pan to ensure fitment... so I am at a bit of a stand still.

That's all for now...
