Just picked up a wrecked 2013 camaro with "LS3" and tr6060 for a steal. I haven't had a chance to pull the engine yet and confirm they haven't swapped the motor, but I noticed 853 head stamps with adapter plates for the intake. I know it's a 4th gen aluminum block by the knock sensor and timing cover, but not sure what exactly I have yet. No other way to prove it's a 6.2 LS3 without separating the transmission is there?

 

The knock sensors and timing cover will fit any LS. Make sure you don't have an early LS1.
Are there knock sensors in the valley cover? If not, still pull the valley cover to see what's there.

 

Is there a way to identify the block without separating the transmission? Would there be a stamp behind the water pump? Or can I pull the intake and valley cover off and notice a difference? I pulled the alternator and bracket off. There wasn't a stamp there or displacement marking. The only thing there was the number 98 with a circle around it stamped.

 

If it's a Gen IV, under the valley cover will be the towers that direct oil to the DOD/AFM lifters, even though they are not used in an LS3.
The valley cover in this case just seals the tops of the towers without handling oil.

 

Thanks for the responses. My heart sank when I saw the 853 heads, but I'm hopeful it's still a 6.2 block. I'll pull the intake and valley cover off this week and take a look.

 

There should be a displacement cast into the block directly to the right of the water pump on the drivers side of the block, right under the cylinder head. It will say 4.8/5.3, 6.0, 6.2

 

I don't recall seeing anything there but the a stamp of the number 98 in a circle, it was small. I'm about to head out and look again. I'll post back. Possible that I need to remove the water pump to see it?

 

Im not sure what year those got electric power steering, but it would be behind the pump/bracket.

 

this is what I see on the driver side

 

Damn. That might be a 98 LS1 block. Do you know any history of the car? Did it ever run? Seems unlikely someone would swap a 58X crank/reluctor on there.

 

I think him pulling the valley cover will be the tell here. Towers, LS3. Knock sensor bosses, Early Gen III LS1

 

My guess will be it's a 5.7 LS1 or a Gen IV 5.3 aluminum block.

 

That 98 stamping just screams early LS1 from an Fbody car.

 

I'll pull the car in the shop and get the intake off this week to find out. Fingers crossed, but I'm doubtful. I know it has a good tr6060 in it. The only thing I know about the car was the guy crashed it and ran from the cops. I got it from the tow guy for 2k. Was really hoping it had the 6.2 for my 71 camaro I'm building. Should have known better.

 

Still a good deal if it has a good TR6060 and a good LS1 in it for 2k. Hope all that stuff is good.

 

On the pic above it looks like the cam sensor is for a gen IV? The LS1's had the cam sensor on the back of the block.
My current LS swap is a 2012 L92 and it has 823 heads.
Here's a pic of the 6.2 from the front. I thought the cubic inch names are on the rear of the block?

 

Yeah hopefully so! The interior is definently worth parting out. I'll keep the thread updated after I pull the motor and get more information. Thanks for all the help guys.

 

that looks good! Yeah this motor throws mix signals to me. I feel like it screams 4th gen by the placement of the timing sensor and knock sensor, but the block stamp looks identical to an early ls1. If it wasn't raining right now I'd pull the intake off outside.

 

Late-style sensors (cam, knock, crank, etc) will all fit early blocks. As was said, it must have a 58x reluctor or it wouldn't work.

 

Just one more thing that points to a gen IV LS of some kind is the ECM shown in the pic above. It's a gen IV ECM not a gen III.
