That is absolutely a possibility. It would be ann LT1 with a revised intake. They could then bump power to 480/485 without stepping on the C8's toes.

It's not just that it's technically easy to re-engineer the LT2 for Camaro. It's also the regulatory side that would have to be done. EPA/DOT, etc...

i don't have a sense for how expensive it would be to put in an LT2, but wouldn't it save costs on producing the LT2 for the C8, and there would be an excuse to increase the price of the Camaro?

Devstrike · 11-12-2021, 06:34 PM

Since there is a possibility that the Camaro is going away and if they did end up bumping the power of it (IF they do not saying they will) I could be tempted to trade my current one for the increase in power.

Well...he explained himself 40 minutes ago...

JKSully · 11-12-2021, 07:54 PM

Still have my doubts - but whether it's a bump of 25 hp or 35 hp, I really couldn't care less. The most powerful car I've had previously had 300 hp / 300 ft lbs - I'm plenty satisfied with 455 / 455. Will not regret getting a '22, and will not be trying to sell and upgrade to an LT2.

Completely agree, I don't think 25 HP gain is enough to change anyone's order or current ownership. I would think it would at the very least need to be around the 500 hp ballpark to even be considered. It does feel as though Camaro team wants to go out with a bang, so will be interesting what the final year brings.

After listening to this new video he just released, I still gotta call bullshit. All the money and effort spent to put a new engine into a Camaro, that has had poor sales numbers, just to gain 25ish horsepower seems ridiculous. Add to that the existing parts shortages and supply chain issues and no competent business would make such drastic changes with such huge questions of when, or if, parts will be available. And, as said earlier in the thread, why would GM announce this for model year 2023 when there is still half of model year 2022 production window still remaining?

Either GM is trying to lose a lot of money or Lethal is full of crap.

I think everyone is making a mountain out of a mole-hill on this one. It's not about making an LT2 fit in a front engine car. It's still the same basic architecture as the LT1, so it's about what LT2 parts really make the power and can they be added to an LT1?

The LT2 makes 495 HP and the Camaro LT1 makes 455 HP. We know the LT1 and LT2 use literally the exact same cylinder heads (same casting numbers, same valve sizes, same compression ratio), so that leaves the camshaft, intake, and exhaust manifolds as the real power difference here.

We already know the intake manifold bolts right up to an LT1 with a few minor modifications and makes ~25 HP. The LT2 camshaft specs are a little bit more duration, so that's a possibility. The LT2 Corvette exhaust manifolds are as much about packaging to fit in the mid-engine bay, thought they probably are a bit better than the LT1 units.

What I would imagine is GM building an "LT1.5", basically the LT2 intake and camshaft on an LT1 making ~480 HP or so. It really wouldn't be hard from a technical standpoint. But it does cost money to re-certify the car for emissions and fuel economy, so the real question is would GM be willing to invest the money?

willzilla · 11-12-2021, 08:28 PM

GM will do the bare minimum, so.. doubtful, lol.

This topic showed up here as well but this shows it as a rumor.

The_Dudebozo · 11-13-2021, 01:13 AM

On a positive note - If they go with the LT2, I guess we could order a Camaro branded engine cover for those who installed the intake manifold to their LT1

samurai · 11-13-2021, 02:25 AM

With a boost of 25hp this rumors is even more obvious bs now. How would anybody suddenly start buying a Camaro if he wouldnt do that before with this minor hp bump?

GMAuthority also calls bs with their own sources:

That said, there are several reasons why this rumor is a bit off-track as well, starting with high fuel economy and emissions certification costs, all of which don’t necessarily make sense for the final model year of a vehicle. What’s more, according to GM Authority sources, General Motors has shifted all development and engineering resources from the Camaro to other projects.

Furthermore, the only transmission currently suited for the LT2 is the eight-speed dual-clutch unit from Tremec currently in use by the C8 Chevy Corvette Stingray. As such, 2023 Chevy Camaro models with the LT2 would require extensive engineering, testing, and validation, which, again, is a hard sell for a model slated for retirement.

Finally, General Motors is running at full chat to build as many C8 Corvette Stingrays as possible, which means it would be an odd choice to allocate LT2 engines towards Camaro production.

Seeing these rumors on a lot of sites now…

https://www.motor1.com/news/547554/c...-v8-rumor/amp/

Big question for you folks. Would some of you trade up to a 2023 (assuming no crazy car market) to get the LT2 or would you just upgrade the LT1?

Another question… Are LT2’s able to handle boost more reliably than LT1’s?

Great point! My plan is to upgrade my IM when I run flex fuel. Having a matching cover sure would be a plus.

Being we can do flex fuel plus IM and get the same or more power, I don’t see a trade in my future for an LT2 Camaro.

However, if it were offered with that rumored “special edition” exterior refresh with a lowered ZLe wing and canards, yes I’d jump all over and it!
