I am very impressed. How many builds have you done? I am in the process of my second restoration, but I can tell you know what you are doing. Just the idea of installing a LS engine is daunting. Thanks for all the pictures and the knowledge you are passing on.

Thanks for the comments..

This is my first build... I have done a lot of mechanic work in the past (long ago) and a couple of engine swaps.. So I am learning as I go... this forum and the people on it are great resources... I would not be this far along without them…

Hey Mark, your cooler lines looked great!! I was wondering where you got your wiring diagram??? (I'm a little concerned)

[Crash_OK]

It's alive...!!!!!!!!!!!!!!! Hooked up the PCM. powered up the fuse panel.. hit the starter.. started right up.... sounds good..

Congrats on getting it running! You know we'll need to see some video.
Amazing how fast you got the chassis done and motor running. It took me a solid year. As soon as fishing weather hits I usually stop or slow to crawl. I'm going to try to stay hooked up this year just to try to keep up with you

Thanks fakerwade.. Which wiring diagram.. the one in showing my fuse box and relays? It is something I created based on the factory wiring diagram.. What is you concern?

Nothing too major,,, it's been a while since I worked for GM so things may have changed. First thing that jumped out on me was that the fuel pump relay was activated by sending power from the PCM to the relay, usually that leg of a fuel pump relay has "key on" power and the relay is activated by the PCM closing the ground to the ground leg of the relay. The second thing was the use of a 20 amp fuse to the PCM through the "hot all the time" side of the fuse box. That power feed to the PCM is simply for memory retention and requires very little amperage to maintain. The 10 amp fuse should probably go there and the 20 amp fuse should go to the "key on" side of the fuse box for the actual power up of the PCM. Like I said, I may be wrong, glad to hear you got it running!!

Update from last weekend.. Built a driver’s side battery box out of what I had on hand.. I am not super happy with it, but it is functionally, and does not look that bad. It did fit well, and is very stable.







I installed new radiator rubber support pieces and replaced the modified 2 core metal support pieces with 4 core ones.




After that I installed the new radiator support mounts.



Next I temporary wired up the engine harness and fuel pump.




Then I fired the engine up.. started instantly.. I used the Scan Gauge out of my Tundra to look for PCM codes and to monitor water temp, loop mode, and RPM.











Mounted the radiator





Sunday I stripped the old cab all the way down and moved it out of the shop … getting ready to bring the new cab in..







I had my lovely, wonderful, wife record the engine startup… Seems she could not keep the camera off of me.. Can’t say I blame her.. But she did get some pictures of it running. The audio is terrible on the cheap camera we were using the engine was much more quite than this video depicts.

Hey Mark, nice work on the battery box. It looks right at home to me. I'm digging the video too. I really want to know how to hook up one of those for my project(s). Keep up the hard work

Thanks Mike.. The welds need improvement.. The battery tray was rusted out in a coupe of places.. I patched those, but there is still some pitting. The PO used a 1973 - 80 battery tray.. it worked out well moved to the drivers sde.

What is it you want to know how to hook up?

[mcbassin]

OUCH! That sucks, hope you didn't get tweaked in the tip over. Or make some new dents. Looking forward to the LS fan setup details.

There was some tweaking and some new dents.. but not a big... small problems compared to some... I loaded the old cab this morning in about 5 minutes..

[Crash_OK]

Started out the day building a mount for the LS1 fans. I had some 1” by 1” angle aluminum that worked out really well.










I used one of the lower shourd clips on the bottom. I think it will work ok.. time will tell..







Then I worked on the wiring for the Fan and Relays…








Started it up and let it get up to temperature. The fan started somewhere around ~195-198~ on low speed and cooled the temperature down to ~191 for the fan shutoff. I will not be able to test the high speed setting until the ambient temperature gets higher and I am able to drive it. I did test it by taking the high speed wire to ground and it worked great.





Finally I started cleaning the bottom of the cab. While this cab has better cab supports.. the floor pans and lower parts of the firewall are worse. I will need to utilize some of the old cab pieces on this cab.

[mcbassin]

Good work on the fan mount Mark. You're gonna have to show me how you wired that setup. I'm assuming you are monitoring the engine temp with your scan tool.

That looks like some 1/8X1" aluminum angle. I have crap load of that stuff in a corner somewhere in my piled shop I would have been glad to give you some. Too bad that cab needs so much attention. I just got finished for the night on mine, it was a long battle. I'll give you a hand with if iI can.

Thanks Mike.. I have it all documented.. should not have any problems.. The fan setup works really nice, I am glad I went this way instead of the mechanical fan.
I had the angle piece laying around.. it worked out well.

No problem on the cab.. 40 year old stuff is going to have rust.. I am still debating on which cab to use.. And I will take all the help I can get… so if you every get bored and want to make a trip to Eufaula I will be there..

Hope all is going well on your cab....

[Crash_OK]

Started off the day by scraping the bottom of the cab..



After that I sandblasted the bottom of the cab…



If you want to find rusted out holes.. just fire up the sand blaster.. I found rusted out holes in places that looked perfect…








Got the cab back on the cradle..







Not sure where to go from here… Thinking about going back to the old cab.. the cab supports are rusted out, but there is less rust overall on my original cab compared to the new one.. Either way there is a lot of work to do… 

WOW! That thing sure looks different after you shot it with sand (black diamond). It all looks so familiar for some reason. It's really not too bad, it's just time consuming. I know I was really glad to get the cleaning stage that you did today done.
