What is the displacement of an LS3? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

As the thread title says, what is the displacement of an LS3?

I remember when I ordered my car, on the workbench print out it said that the displacement of an LS3 is 376 cubic inches.

However, when I looked at the specs on the camaro website, it says that the LS3 has a displacement of 378 cubic inches. Also, when I googled 6.2 liters to inches, it says 378 inches.

So, which one is it? I am interested because I want to get a decal for the cowl that says the correct displacement.

According to GM:

It's 376.

Well they claimed the ls1 as a 5.7 but it was 346ci. Also the 5.0 mustang was actually a 4.999999.

Cool, thanks. that's a pretty neat spreadsheet.

376 cubic inches

6.16 liters

GM just rounds up on the liters.
(6.2 sounds better than 6.16)

More or less yes, the L99 and LS3 are the same at their core, but they have different compression, lower rev limit on L99, AFM on L99, etc.

go OU
