84 "LS1" Engine Swap/Build **PICS**
 
Well after some research I have decided to do an "LS1" Engine Swap/Build. This was the thread that convinced me to do this swap...
Click HERE
and I started to wonder if anyone has done this swap in a C4. It turns out that corvette fever has done this swap in a C4 and its called Project C4orce. Once I saw that I knew that, that was the engine swap I wanted to do. The reason I'm not doing an actual LSx swap is because it is too much money for a high school kid.

So today I managed to get down to the junkyard and pick up an LM7 327 (5.3L) engine from a 2000 Chevy Silverado 1500. It has 52k miles on it and cost me $600. It seems to be in good condition and everything but I have 30 days to return it so I am going to be doing compression test and a leak down test first. Once its good I will be swapping the truck intake for an LS1 intake, fuel rails, and injectors that I bought used for $130 (still waiting for it to come in the mail). All I need to get the motor running is a LS1 harness and ECM then it will be good to go for the swap.

Here are some pics of the motor the way it is now (how it came from the junkyard)

It came with everything besides an alternator and belt.

Enjoy :cheers:

:agree: You will need to swap out all those truck accessories for Corvette ones, get a Camaro oil pan and motor plates to bolt the motor up.:thumbsup:

I plan on getting the motor plates and would I be able to use a 2000 WS6 Firebird oil pan?

Yep, any LS F-body oil pan you can also use the stock Vette pan of you aren't going to run headers. The F-body pan is more like a traditional small block pan that's why they are so popular. That truck pan might fit but it will hang way down.

Jeffvette did the swap in his 1991 racecar.. he used a T56 in his build

How much of the trucks accessories are not needed? I thought I would be able to use everything besides the alternator bracket and the A/C. And the fan obviously.

Judging by how this project goes, maybe you can build me one too! :devil: :thumbsup:

Get your free subscription to Corvette Enthusiast and look up the December 07 issue (the first of two) that covers how I installed a LS2 in a 1985. My method differed from that of Corvette Fever on a variety of levels to allow for use of stock accessories and a/c, driveshaft (without cutting) and less expensive motor mounts, headers...etc.

We were able to retain all factory gauges (except the fuel mileage calculator) and keep it all under the hood.

The main trick for us was doing some simple mods to the cross member to allow for the a/c compressor and $4 each dodge truck motor mounts to hold it all in place.

The car ran like a screaming eagle...but idled and blew cold air like a caddy. It turned out to be one of the cleanest swaps I have ever done.

I used a fellow named Jared at www.currentperformance.com to merge the harness and make all the electronics happy. He is a tad more expensive...BUT, when he sends it back it is a one and done harness that plugs into the factory connections - no splicing.

Good luck...have fun!

Oh...by ALL means...do your compression test, etc, NOW. I am doing another swap for the magazine on an ebay 8.1 vortec. I "assumed" (you know what that means) it was a good ebay engine. I didn't test it first. DOH! Anyway...got it fired up and pumped a gallon of water through the cylinders and am still battling getting the heads wrapped up...etc. UGH!
