My super awesome money pit project

bored and figured what the hell...
let's update this.

Recently the 2000 LR4 4.8L I had in it lost oil pressure, think it was the pump but didn't want to invest in tearing the engine down and it being something more than that.

So I got a "new to me" 2004 LM7 5.3L from a auto recycler with 142k miles on it..
It had cracked castech 706 heads which I was able to reuse my old 862 heads, I did lap the valves and change the stem seals while I had it all apart.
and I had to swap out the water pump since it's bearings were GONE..
also upgraded my transmission crossmember to a brand new heavy duty G-force piece.
While I had everything apart I also went ahead and cleaned up the ghetto ass wiring, got rid of the silverado fuse block and new just using a single relay for the fuel pump and 3 10amp circuits for the pcm keyed power.

took me nearly a month to get it all in and just shy of $1,000... but as of now it's 99% done just needs a few new exhaust clamps, air filter and the hood needs to be bolted on.

And.... here is a clip of it running today after I got everything put back together.
