5.3 LM7 going in my 87

[fried_daddy]

Starting this thread to document my journey on my LS swap. I have a few pics on my build thread but i'll post everything here. Purchased as a pull out from a salvage yard in Greensboro, NC. I bpught the engine, computer, harness, and a 4L60E transmission. I'm still in the air on if i'm going to use the 4L60 initially or not.

Pulling the accessories off and removing the harmonic balancer. I had a few exhaust bolts broken off. Removed 2 with a pipe wrench and I had to use a EZ out to get the two out that broke off flush with the head.

I had to order a new starter because I broke the bolt off mines when I was removing the battery cable.

Cylinder head on the bench after removing the springs and valves. I reworked my heads the hard way. All manual labor.

Couple tips.

go ahead and get a chevy 350 test stand like the one below. When you get your harness done you'll be able to start it on it. I used dirty dingo mounts and had to flip them L/R to make it fit but it was easy.

Also, if you don't want to rig up a fuel pump for the test when you get to it, get a gas (oxygen, air, helium...whatever) cylinder and put a fitting at the top with a regulator so you can hook up an air compressor to it. Drill a hole in the bottom of the cylinder to run to your fuel rail. Hook up your compressor and adjust it to the psi for your fuel. Then fill it with gas, hook up the compressor and there's your temp fuel pump.

On the same theory above, to prime the engine with oil do the same thing but at around 10 psi with all sending ports plugged....I learned the hard way and got about half a gallon of oil on the house floor. The plug to hook up to is on the drivers side front below the exhaust if I remember correctly. this will prime the engine with oil to everywhere it needs to be before you fire it up.

Take the exhaust and spray them with Ospho and let sit over night. Wipe them down with a new/clean rag and paint with Rustoleum Extreme high heat spray paint. Mine still look good.

Looks good, keep the pics coming.
