LT vs LS engine: What are the differences and which is better?

Let’s find out which GM-made V8 engine is worth its salt in this LT vs LS engine comparing article.

The differences between the LT vs LS engine

We’ve talked about the LS engine before. If you read that article, then you’ll know that we practically gushed about it. It is, after all, one of the best GM products ever made, and is also probably one of the best V8 engines that money can buy today.

But what about the LT engine?

Now the LT small-block V8 is currently in its fifth-generation, and like the LS, it is also made by General Motors. The LT as a product designation, however, came out much earlier in 1970, and the name was later reused for a newer V8 called the LT1 350 in 1991. The latest one, however, came out in 2014 and it is known fully as the LT1 Generation V.

Why the LT engine is even better than LS, and may be better for you.

For the purposes of this article, we’ll mainly be talking about the Gen V LT1 vs LS3.

If we compared LS vs LT engine in terms of construction, then the LS3 motor uses aluminum in its entirety. The same is the case for the newer LT1 Gen. V. While retaining the same 6.2-liter displacement and the same 4.40-inch bore.

The LT1 Gen V’s camshaft features a new cylinder head, a new tri-lobe camshaft, as well as a new piston design. Combined with the new high-pressure oil pump, the said engine can also introduce more fuel into its cylinders, thus having the potential for higher horsepower outputs.

Also, of note on the LT1, is that it now comes standard with variable valve timing. Compare that to the LS3, which only had VVT on specific car models. One example of which was the 2010-2015 Camaro SS with an automatic tranny.

Specs	LS3	LT1
Displacement	6.2-liters	6.2-liters
Max. Horsepower	426-430	455-460
Max. Torque	576 Nm	623 Nm
Peak HP and Nm RPM	4,500 rpm	4,500 rpm
Bore Size	4.065-inches	4.065-inches
Price (Crate Engine)	Php 377,701*	Php 407,029*
Head Material	Aluminum	Aluminum
Block Material	Aluminum	Aluminum
Compression Ratio	10.7:1	11.5:1

Note: Before taxes/Price for LT1 is for the Wet Sump version

LS vs LT: So which is better?

If we’re talking about raw power per liter, then the newer LT1 offers more. At the same rpm range, the newer V8 can offer around 30 more horsepower. If what you’re after is more power without relying too much on forced induction, then this will matter a lot.

Apart from that, the LT1 comes standard with VVT. For those who don’t know what VVT is, it is a system that controls the intake of fuel and air. With this system, the engine can offer better fuel mileage and a slightly lesser carbon footprint depending on the use of the car. For a thirsty and relatively high displacement V8, this can be a godsend.

The LS3 and the LT1 both produce their max outputs at around the same rev-range

One huge disadvantage of the LT1 Gen. V is that it’s a newer engine. In terms of LT vs LS, it has lesser available aftermarket parts. That however is slowly changing, and manufacturers are catching up. Of note, crate versions of the LT1 Gen. V are already for sale.

Do note though that the LT1 has a higher compression ratio than the LS3. This means that the latter’s components are subject to more stress, and if things go wrong, engine knock is more likely to happen.

While that may be the case, higher compression ratios also have their own advantages. In the case of the LT1 Gen. V, this allows it to make more torque and horsepower. Also, it provides greater efficiency of combustion. Combined with the VVT, this might mean that the newer LT1 might be more fuel-efficient than the LS3.

If we’re talking about local availability for LS vs LT engine. Then it might be easier to find an LS1 engine. It's been around longer than the LS3, which in turn has only been available on the 2016-2021 Chevrolet Camaro SS, and on the 2014-2019 Chevrolet Corvette C7.

The bottom line, however, both of these engines can be expensive to import into the Philippines even in crate-engine form.

If you have deep pockets though, you can buy a used PH-spec Corvette C7 (equally hard to find) and then scavenge it for its LT1 engine. Just don’t let the local Corvette fans know of what you’re planning to do.
