Engine RPO codes are tricky. Today trucks have 2 RPOs for 5.3L and 2 RPOs for 6.2L and GM has no issues with mixing and matching those. The difference is that some have AFM and some have DFM. The differences between LT1 and LT2 are likely to be even less. Also GM has several plants building the Small Block V engines. Tonawanda, St. Catharines, Spring Hill, Silao, and even Bowling Green for the customer involved builds.

It would be simple to have LT1 built in some locations and LT2 in others to avoid confusion and build complexity in the plant. Even though it might be simple to simply place the LT2 in Camaro at the same time as in Corvette, it is probably more profitable to do it at least a year, and probably even a generation later. At this point it’s more about revenue than it is about cost.

You are correct, it's easy to have two separate engines.

However, the LT1 volume, and time on the tools required manufacture the engine, would drop in half. So instead of 1 engine at 40,000 units, I get 1 engine and at 20,000 and another at 20,000. Based on modularity, they could easily build the two on the same line. With current manufacturing processes, it's easy to build that way. I'm merely suggesting at some point, you don't want two high performance V8 engines.

I don't disagree, they likely won't launch them at the same time, and may simply wait until a Gen7 to introduce it.

I think most here will agree the LT2 will find its way into the Camaro but I’m still thinking it will be in the next GEN. Also GM had no problem making the LS3 and LT1 until Camaro moved from the GEN5 until the GEN6 came out.. right now only GM

Yes and they even maintained LS3 production for the SS Sedan through 2017. Would love to have seen that move to the LT1.

LT1 to LT2, as you point out since we know nothing about it, could be a mouse or a house. If it's the same block architecture, more like a mouse. If it's an all new block, etc., then a big house.

As always, time will tell.

GM just spent a chunk of money to increase V8 production at Spring Hill. The official line is addition of DFM capable engines, but I think some of that is for LT2. I would also expect they will add LT2 to BG. LT1 is already built at Tonawanda and that tooling is already bought and paid for and coexists with tooling for LT4 and for the truck V8s built there. There’s another plant that also already builds LT1, I just don’t remember which one that is. The addition of 1LT LT1 might also be way of replacing some of the Corvette LT1 volume that moves to LT2. That’s a stretch, though, since that would imply 20 - 30,000 additional LT1, but I would not be surprised if some additional LT1 volume was a factor in the timing of LT1 model introduction.

I’m also doubtful that LT2, if announced in July is the basis for all engines the C8 will see. It just seems we will also see a line of OHC engines that take the C8 to a whole new level. So I don’t think the question is whether the Camaro sees whatever the C8 base engine is, it likely will, it’s just a matter of when. The question is does the Camaro ever see a DOHC V8? Or the rumored 1,000 HP C8 drivetrain?

[SecondZ28]

I’d guess GM will likey just overlap old/new production for LT1/LT2 like they have consistently done in the past when introducing a new engine in Corvette

- 1992 (L98/LT1) (Camaro/Corvette)
- 1997 (LT1/LS1) (Camaro/Corvette)
- 2008-09 (LS2/LS3) (TBSS/Corvette)
- 2014-15 (LS3/LT1) (Camaro/Corvette)

I see no reason for a DOHC eng. for the Camaro. It will be bigger and top heavy with less torque.

All the whining and "major" changes, and the 2019 is still the most aggressive looking SS made.

At least now, we can get some actual worthy threads going, hopefully. Got kinda old when all the threads were the same BS.

How many people have told you you car looks ugly, vs. how many have said it looks great? I liked the earlier looks, and the 2020 SS is ok, too, but I like the 2019 better and will happily keep it until I go for a ZL1 or future Z28.

Blackwing V8 is apparently smaller than the LT4.....

Like it or not, DOHC is the future. Maybe not totally until the 8th gen as LT2 will probably be OHV still, but chances are the next ZL1 will share the C8 Z06(?) engine which is rumored to be DOHC. I don’t see GM being too divergent in their performance V8 family. Heck I could see them switching entirely to DOHC eventually in order to keep costs down by having the trucks provide the volume for the architecture.

Off of the same block architecture, adding an engine that mounts the same, transmissions are the same, finished engine weighs the same and is simply internal changes for FE or performance is not as big a deal as an all new engine. A ton of calibration, yes. But structurally validating the body is less of an issue.

If the LT2 is the Corvette "base" engine, I don't see it being any different than today where both cars get the LT1. Now the up level offerings is a different story.

Also, does GM want to make an LT1 for the Camaro and an LT2 for the Corvette? That just makes the LT1 and LT2 both more expensive. And as GM is about profit, we can hope they pick the more cost effective solution.

Wasn’t the LT2 listed in the leaked ordering guide? I know those preliminary guides aren’t very accurate but at least it’s some proof an LT2 is coming.

The Blackwing was built entirely around minimizing the engine size for the 4.2 liter displacement. It has a small bore and long stroke. Even then, I think it weighs about as much as the LT4.

The weight being similar isn’t too surprising. 1 cam + a supercharger + cooling vs 4 cams + 2 cam timing chains + 2 turbos + cooling.

If Corvette base engine becomes DOHC expect that to become the Camaro engine as well. that is just the way it goes.

I expect the LT2 to be a improved version of the LT1 so I would expect the OHV to stick around for a while

I'm sure you release that other than the LT1 / LT4, Camaro engines are already DOHC. And so are all Mustang engines. They clearly don't lack for performance. I trust GM to know how to engineer and produce DOHC engines that can make the Camaro sing.

That's what they said when the C4 ZR-1's LT5 came out....30 years ago
