I bought a LSX motor!

[Andy4639]

Well as the title states I bought a 2003 6.0 LSX motor & 480 transmission with 89,000 miles on it. I also got the computer that has already been sent off and redone along with wiring harness. Motor mounts, new fuel pump.
I will be buying a radiator to fit the new motor with all the right connections on the right sides. Any and all comments welcomed for I have to learn how and what I need to get this going. It's going to take awhile but I have until next June before I have to be done.
I want it in and going for the 2014 Power Tour.

[Andy4639]

I also got the o-2 senors, oil cooler lines and all the AC lines which I don't think I will be able to use. I will be adding to this as I get stuff done.
Any suggestions comments please advise me on what I should look for are need.
Looking forward to this install.

Lucky dog! Andy if I read between the lines the 71 is going to receive the transplant right?

[Andy4639]

Yes the 71 is getting a new heart beat! Want to have it up and running by next June before the power tour starts!
The old 305 TPI is needing a whole rebuild so I figured this would be a better way.

Do u have any suggestions on the install.
It's going to be a slow build at first because I'm fixing to start 6 -12 at work for a few months, but it should pick up after the first of the year.

Let the fun begin!!! I was thinking if I get my Blazer done in time I may take it on next years Power Tour.

The PCM says 2001, and the engine looks like it's DBC, so I would say it isn't a 2003.

Also, some custom fabbed lines on the factory A/C compressor and you'll be good to go since you've already got a modified system without the POA. I have about the same set up and it will freeze you out of the truck on the hottest day.

If you have any specific questions, hit us up, there's a lot of conversions been done on here.

DBC - drive by cable
DBW - drive by wire ie, electric pedal

In 2003 GM started changing over to DBW, but not all vehicles were switched. Vans, HD trucks, mostly commercial vehicles were still DBC, at least based on the info I have read.

Nice

If you and a friend get serious, yall could have the old out and the new in in a weekend. another weekend to plumb the fuel and stab the radiator in. Next thing you know is your driving it.

Andy, a cold AC will be a good thing, esp like the temp was in Bham on this past POWER TOUR. huh...

[Andy4639]

Yes I plan to have everything hooked up on it when done. My main thing is having to wait to start on it since I'm fixing to start a outage at work.
I want and try to have everything I need up front for the install so I can try and get it done in about a weeks time. Don't want to be waiting on parts. I know I want have everything but I want and try to cover most bases.

that red print is hard to read...

Andy, its really not that much different than any other motor install. It will fit, you may need to do some trimming on the frame rails to make it all fit. But that will be minimal. The AC can be a bit tight. I got mine in and it sits between the rail on the passenger side. It is tight but I can get it in and out and works great. Keep in mind I built my own mounts so my motor is not in he same position as anybody elses, so what works for me and other will be different than yours.
good luck
Dave

[Custom 68]

I will post pictures this weekend my notch is more like a small grind area around the exhaust manifold ends. I didnt notch for my AC but it is tight. but yes I understand if you dont have to that is great.

Congrats! I am envious.

[Andy4639]

Well I'm going to have Shon do the install I think. We talked about it the other day and he has done several already. Hope we can work it out and get it in by the end of the year.

Moving the compressor to the top requires a special nracket and longer belt. If you go with a Kwik Performance bracket, it also requires an F body tensioner. Not sure about Holley or Dirty Dingos. You may also have to get a new compressor,depending on what you have now. The one that came with the 6.0 won't work up top, but if you have the Gm "pancake" type compressor which would have been on a TPI engine, they make brackets for them as we'll.

I have the v belt sanderson. I bought it and the brackets from VA.
I would have to see if I could put the other pulley on it and buy the bracket for it. Then I could keep all the lines as they are.
