LS7: All Air Monster

The LS7 is the largest engine offered in the LS street production line up currently at 427 cubic inches.
This engine shares little with the other Gen IV engine other the basic design. Everything about the bottom end
of the engine is light: light weight rods, pistons, and even the crank is lightened, all for better NA performance.
Up top the heads are all unique to this engine, with hollow stem valves and ports that do not share much with
the LS3/L92. The list goes on from there as this engine has a strong history in racing and a lot of technology.
From the factory this is the best engine from GM for unmodified/un-supercharged performance.
I mean the engines are even all hand build. That is something you don’t hear everyday.

Now, that being said. The LS7 is an expensive engine. For my projects, I will go with the LS3 – big power for an
everyday price. We have had a few LS3’s come through our shop, and with only a few upgrades such as intake, exhaust,
and a cam, they make as much, or more power than the stock LS7.
