The Black Pearls LM7 5.3 LS SWAP!

This is the first time I've ever welded with 16g and also the firs time using .025 wire so my welds look like crap.

We have a fancy new smoke machine at work. I am going to bring the manifolds to work and smoke test them, and weld up any pinholes with the shop welder so I know the system will read correctly.

Finally got my plates in! They have been sitting at the licensing office since about August and no one knew.

Holding off on the Eco-box for now, so i decided to get the slip-yoke eliminator setup going on the NP241 transfer case. The output shafts are heat treated a few millimeters into the metal, so I cut about a 1/4 off the back of the shift, and drilled and tapped the center.

I got the trans and power steering mounted, nothing spacial on this side.

I did get the factory explorer steering box rebuilt and drilled/tapped/plugged for future hydro-assist.

I had the local napa auto parts build me a custom power steering pressure hose, from the LS pump, to the explorer gear box. There are a few inches of each factory hose/line (to use their respective fittings) and then to a very common hydraulic JIC -6 mating ends. I was assured that these are the absolute most common fitting used at any place were hoses are built so it will be very easy and cheap to build a replacement while on the road/trail.

The rear driveshaft is about 35-36 inches long, I found one that was freshly rebuilt. The front driveshaft from a 2010 F350 diesel is only a few inches longer, requiring a cut and balance. They use 1350 joints and is double carden so it worked out well.

Before getting the rear driveshaft back from the shop, I decided to pull the truck out and get the shop cleaned up which marks the first time the truck has moved under it's own power for the LS swap. Front wheel drive only and no fluid in the brake system but hell it moved.

I have a few videos that I am unable to upload them to the forum.
 













Needed to clean the shop of Really Bad, and figured the best way was to move the explorer out of the shop, so I threw a bunch of stuff together and moved it for the first time.
Dont mind all the hoses and everything, still a lot of small stuff to do.
 












Amazing. It sounds good, dude
Thanks. Nothing too spectacular about the engine, lots of upgrades to the valvetrain for "reliability"

It's a hell of an upgrade over the OHV, and that's spectacular enough

Yeah I originally bought a 5.0 out of a 95ish f150 but it was only like 100hp for all the work, and my buddy had built 5.3 in his drag car that he got tired of, and into guns so I traded him a ar15 truck gun straight across and we drove his car to my shop that weekend, pulled the engine and flat towed it back to his house a few blocks away.
 






Well finally got the transmission cooler lines ran. -AN fittings at the th400, 3/8 high pressure trans fluid hose, several feet of ~5/8 split loom and a couple P-clamps secured with 1/4-20 rivnuts to the inside of the frame.

A little sneak peek of an awesome project for the Black Pearl. Thanks to @gmanpaint and all the hard work he did on it, and for the piece de resistance that I just got installed, it REALLY ties it together.

IT LIVES!!!

FINALLY got the first LS swapped explorer on the road! AND it's "legal" lol.

It's got some pep in her step. Trans is shifting well, I can actually bark 2nd gear on dry pavement, but I run the risk of breaking the lugs inside the trans case so I wont be done that anymore but at least I've got some bragging rights!

The steering/alignment needs to be tweaked a little. Above 55ish it's a little sketchy. Got it up to 70 mph and that was enough excitement for me.

There is a little drivetrain vibration at 50-60 but I noticed NONE of my tires have wheel weights in them.

The body roll is white knuckling, definitely need to get a front/rear sway bars at some point.
