Before & After - My 1993 K1500

93 Krawler · 05-26-2015, 12:45 PM

I checked the heads for cracks and didn't see any. I did this as a preliminary check in hopes of seeing something obvious. Since I didn't, off they go to the machine shop to be cleaned, pressure tested, and checked for flatness. I'm taking them tomorrow to Performance Engineering in Hamilton. I've heard good things about them. https://www.facebook.com/PerformanceEngineeringLLC

Got the heads back. They said no cracks, but needed to be milled.
Lapped the valves in myself.

Got the the engine, trans, and t-case out. Time to put it back together.

The VSS that is on the tail of the t-case won't work on this setup. I had to drill and tap the t-case adapter for a VSS. This will keep the correct speed even in low gear so I don't have messed up shift points. The t-case has a switch that sends a signal to the PCM so it knows it's in low gear, but the new pcm doesn't have this signal so I can't use it.

My tie rod and steering ram was behind the axle, and I had minimal clearance between the ram and oil pan on the old engine. The 5.3 will be moved forward 1" because of the new t-case adapter is 1" thicker. So the tie rod and ram had to be moved up front for oil pan clearance. Mark, aka Waffle, moved it up front for me. Now I have to watch out for rocks hitting the tie rod. The plus side is I can lower my bump stops some since I don't have to worry about my oil pan smashing my ram anymore.

The PCM is going where the coolant bottle is. I will have to get a smaller one and relocate it. It should fit nicely there.

This is what I'm using for my fuse block.

Trans and transfer case are in. Thanks to the engine mount adapters, everything lined back up in the original locations.

So far the only things that didn't bolt back up are the trans shifter linkage and the exhaust. The new trans has the module on the side so the bracket hits it. The exhaust should be an easy fix.

It's taking a lot longer that I anticipated.

I'm missing wheeling trips.
