Bummer man…
someone find me a cheap 6.0 locally!
I would love turbo ls1 ss’s cammed 5.7 but i already have a cam and i am poor.
autopsy continues. wife wants to see what happened and helps.
ok, something to keep us busy while I wait for parts to come in. I found a set of flat-top Corvette LS2 pistons and rods, which will give me a nice bump in compression (i was running the factory “truck” dished pistons before)
some pictures I had on my camera before the motor died. Life was so good!
Finished my exhaust sometime in March and threw some VHT flameproof on it.
few items came in from ECS
the old coolant bottle didn’t look great
30 seconds later, voila
New kidney grills to replace old slightly cracked parts
I had a few extra minutes so I moved my hose reel in the garage to a more convenient spot. My wife kept banging into it with her car door and would have continued to do so until ALL the paint was removed from the door, so a change was in order.
tidied up the garage, washed the car
his and hers
back to reality, some pictures of the motor pull
After 90 minutes we were here

Day 2 after work
now the autopsy
LH head, [URL=http://www.nyspeed.com/usertag.php?do=list&action=hash&hash=5]#5](https://flic.kr/p/rn8WEq) . Valve put huge gouges in the combustion chamber. Luckily, these heads are readily available (and cheap!) so replacement will be easy.
luckily the timing chain was in one piece, so I was confident no other valvetrain was damaged (sure enough when I pulled the other head off, everything was great)
the windage tray was not so lucky
and for the grand finale…not one broken rod, but 2!
When the first rod broke, a piece of something must have gotten into the path of the rod next door rod, and knocked him out too.
Took a break from the motor work to bring home a new toy
Technician117 finally sees the light and brings over some GM power
Mockup - still need to decide final placement and plan new pads for the posts
Kick Ass
Cant wait to see this all complete.
Thanks for buying the neighborhood a lift…I was getting sick of jacks and stands…
Gotta ask… how are those motor mounts that everyone was dogging you on holding up?
Which brings us to this past weekend. Was cleaning up the garage a bit on Sunday morning, on a whim decided to hop on the local Craigslist and do the usual search for “6.0”. Lo and behold there was one locally for cheap, with a “slight knock”, For my purposes, perfect! It came with some nice parts that will help recoup some costs. Loaded her up and had it home before noon. Not much info on the motor other than that it “came out of a steak truck” (LOL) and had aluminum 317 heads (so, it was at least a 2001+).
Yanked the intake and heads and checked bores, they looked great for unknown mileage.
Removed the remaining 15 valve springs at my super fancy cylinder head service bench. Wine and cheese come standard
Awaiting these LS2 full floating rods/pistons, should be here tomorrow - can’t say no to more compression while I’m in there!
Tonight I’m borrowing a friend’s engine crank to finally put the new motor on the stand. I had my old man drop off the power washer last night (and fixed a broken switch on it), so as soon as it’s completely torn down, I will drag the block over to the neighbor’s front yard and start cleaning it up.

One side was almost completely cracked through due to fatigue.
Just kidding, other than some surface rust, they are in perfect shape
lol, good.
But PBR is better in a can…
Dual valve springs this time bro
Looking good
I need to stop and get some today. Running dangerously low on beer. I think I am in the single digits.
Texas Speed is sending me a new set of .650 duals with titanium retainers, seats, and seals for free
I can’t hear you over all the freedom in your garage
so, a quick non pictorial update. I decided to go with some new pistons rather than reusing the LS2 stuff - and since the oversize units cost the same as the regular 4.00" bore, I decided to have the cylinders bored .030" over for a 370 build.
So here’s the rundown on the new motor
2002 LQ4 Iron 6.0 pulled from “steak” truck - craigslist yeehaw special.
Stock crank, .010 undersize mains
Sealed Power Speed-Pro flat top pistons (4.030" Bore)
Stock gen 3 rods, LS6 rod bolts
New Clevite P rod bearings, cam bearings, main bearings, etc
GTO oil pan, pickup tube, windage tray
Sticking with the same cam, TSP 228R (228/228, .588/.588 @ 112*)
Top end:
317 heads milled .024” for 66cc chambers
No porting, stock otherwise
GM 6.0 MLS headgaskets
ARP headbolts
TSP pushrods, dual springs, titanium retainers
Intake:
Stock LS6 intake manifold
LS6 throttle body
3" pipe with stock LQ4 MAF, cone filter
Stock LS6 fuel rail, with 42# Ford Greentop injectors
Exhaust:
CTSV cast iron manifolds with the cats removed, into OEM BMW exhaust with 2 secondary cats.
3" QTP Cutout/exhaust dump before all mufflers/ resonators
Motor is at the machine shop now, I will be doing the top end assembly myself. Still need to tie up a few loose ends before it’s ready for the car, like this:

What machine shop did you go with?
always enjoy this thread :tup:
@LZ1 I took the bottom end to Paul at J&L. He’s OCD but I’m ok with that. He’s been more than helpful so far. Heads are at Klispie’s, I used them in 2012 when I skimmed the first set and was happy with it
quick update - between the day job and working on the car I am pulling some 16+ hour days here (and will be for the next week)
the good news is that things are moving right along with no issues (aside from misplacing my tube of RTV and spending 45 mins looking for it).
Tuesday 6pm, motor picked up from builder. Bottom end (crank, pistons, rods) assembled, otherwise a totally bare block

Tuesday 11pm
Block cleaned, masked, painted, all block coolant and oil plugs installed, oil tray on, cleaned and prepped oil pan/windage tray/pickup tube/oil pipes. Head dowels in. Crank and cam sensors in, along with valley cover and knock sensors. Had to call it quits as I was waiting on the oil barbell plug and a new timing chain. I love Summit Racing

I am taking a ton of pictures with my other camera for documentation’s sake but don’t have time to make my usual very long winded post so those will have to wait until a few weeks from now
Hurry so we can cruise and hang out at car shows in lawn chairs like old men!
Looking good Norb. Have enough spare parts to build me a 5.3 for the mustang?
chair is already in the car (not joking)
Actually I do…i have a ton of junk in the basement
