David Ruff  Mechanic by day. Still a mechanic by night. There's no rest for the best! OB member #4542

So here lies the fruits of my labor. A massive pain in the ass to do, but worth every last drop of blood sweat and tears. Again, pay no attention to the pos k&n cold air intake.
The build- #mamagetsaheartbeat
The build sheet- 2005 stock lm7 block that had not survive a nitrous blast from previous owner. Block was bored .040 over. Keith black flat top .040 over hypereutectic pistons, scat forged 4340 I beam rods, a 2002 5.3L crankshaft. Sealed performance moly rings, BBK 85 85mm throttle body, Dorman replacement intake manifold, Texas speed stage 2 low lift 110 lsa, Chevy performance lifters, pacesetter 1 3/4 primary shorty headers, Manley double roller timing chain, melling high pressure oil pump, msd street fire coils and 8.5mm plug wires

She drives again! Now the break in period begins. The engine feels so much better and alive. #mamagetsaheartbeat is now running.

So update for mama, it's alive! Obviously there's a video of it running. The reason it's idling at 850 instead of 500 is because I bought a belt just long enough to be too long. With the smaller harmonic pulley I need a smaller alternator pulley. To make the belt work, I have to put the regular pulley on. The MSD street fire coils pull so much current the truck is idling up to account for the current draw. It has a slight overheating problem, but I had that with the original engine, the mechanical fan just doesn't move enough air at idle, now slow it down with a 15-16 year old radiator that has probably never been cleaned....you can see where that'd lead to an engine running a little hot (200 instead of 180). We also had one hell of a scare, there's a piece of plastic that covers up the torque converter and flex plate. I put it on in between runs. Well when I started it the second time, it made a sound that sounded like a rod knocking. There's was such a sigh of relief when there were bolts scrape marks on this plastic, took it off, sound disappeared too.

It's hit that time folks! It's alive. Cam doesn't sound that big because it's idling 750-850

I like to call this, small block in! The machinist pulled it off and I was able to rebuild the bottom end, and put the engine back in. It's bolted to the trans and sitting in it's own mounts.

So, in admist waiting for a crank, I broke out my painting skills. Granted this is a quicky with electrical tape rags and a piece of cardboard instead of masking tape and paper, it still turned out decent. Because if I'm gonna put this much time into it, it's gonna be the colors I want damn it!! #noregerts #chevy #ls #lsx #lm7 #chevyred #orisitorange #chevyorange

If anybody needs a crankshaft for a 99 or 2000 5.3L, you can buy this one, it's polished and balanced. Otherwise I'm gonna turn it into a table.

Didn't think I'd be seeing this bottom end any time soon.

Yeah, like the caption says. Breath takingly fucked. The flange that the flex plate bolts to is .300 too long. Luckily my old crank is in spec so hoping the machinist can get it polished and balanced tomorrow. Still doesn't change the fact I got to tear down 2 bottom ends.

Aggravation!!! Guess which ones broke and which one is the wrong sensor. The fuckery at autozone knows no bounds. Corse it's my fault for not checking the box like I always do on this one occasion.
If it weren't a new engine or a pita to get too, id run the broke one to the parts store

Mama is heartless right now....and down a leg. And in the bottom corner you can see the sorry #kandn air filter that's coming off as it's only been filtering bugs!
Swapping everything over from one engine to the next right now, looks as I'll be putting it in tomorrow 😀

Literally 6 bolts holding this engine in. Just waiting on my helper to take the hood off so I can proceed.

Got the injectors and fuel rails mounted to the new intake, mama is very close to getting a new heart.
