Another PLUS for the 700-R4 / 4L60E is the low first gear.
These trannies CAN be built to handle *lots* of HP & TQ.

It is expensive to build a good tranny, though.
I had a good TH400 core, so my choice was pretty easy.

I'd find a TBI 350/ 4L60E from a '93-'95 pickup and a set of Vortech heads.. build a Vortech headded TBI 383. you will need the GMPP conversion manifold or a 454 4bbl-TBI adapter plate and a Carb- Vortech intake manifold.. the wiring can be removed and transfered fairly easy, and it will need a new
chip. but with the right cam. it will run quite well

you could also run the TBI heads, because they operate best below 4,000 RPM, and that would be just about perfect for crawling.
Oh no! Not wires! Wires are so scary!

the 5.3L combo is better than the TBI combo in just about every respect. I still think you should go turbo diesel but the 5.3L combo is a very good gas engine.

Buying a complete 5.3 and 4l60e pullout. It's local, low mile, and I got a screaming deal on it. To solve the fuel pump delima, Im going to run stock external pump from isuzu npr. That way when it takes a poo, i can change it quickly. I will post up pictures when I get the drivetrain delivered today.

Thanks for all the help guys, I think I'll continue to post my build here since I'm sure I'll run into problems, and need expert advice. Or should this be moved to a different thread?

Just starting a build thread here because I want to document the process and I'm sure I'll need alot of help along the way.

The plan: This might take a while, slowly buying parts. Still not sure on whos gonna do the welding for me (anyone wanna help in the PHX az area???)

General idea so far (very general...)

5.3l complete legal swap
4l60e + Advanced Adapters to stock split case
Howell harness or ?
motor mounts AA or custom
x-member AA or custom
Aftermarket radiator/tranny cooler
Custom PS and AC lines
All aftermarket gauges on custom dash panel
Havent started thinking about small stuff just yet

I have finally gotten the ball rolling on this project. I have been tearing things off the truck, and just today aquired a fully dressed 5.3 and 4l60e for a screaming deal locally!

2004 5.3l gmc sierra 53,144 miles and 4l60e (4x4 version).

Complete from head to toe (need gas pedal and TAK)

Couple questions before I get to the pictures.

1) Are there any alternative to AA split case adapter?
2) Tranny is 4x4. I was told i can swap tailhousing to 2wd to use AA's adapter. Is this true?
3) I want to use rubber motor mount style, but have heard of strength issues. Any other options?
4) What is the key in the mounting location? Is it to get drivelines straight? Do I want it perfectly center in the frame rails?
5) Will the stock exhaust manifolds fit? If not, what other options have proven to work?
6) I have a billion questions I'm sure... but anything you guys would have concerns on parts wise?

Transplantee prepped for surgery!



Donor Heart!








More to come hopefully soon!

If I could now offer a suggestion, it would be to start a Project Journal right here at Hotrodders.com.

You'll find that it's much easier to maintain, to add pictures and updates etc.
The best part is that it will be asily accessible, both for you and for any other readers that might have interest.

As you can see, a link to my PJ is displayed with every post that I make.
