5.7 liter = 347.8 rounded up to 348 cubic inches
6.0 liter = 366.1 rounded down to 366 cubic inches

A high school friend of mine had a Mach 1 mustang with the 351 Cleveland in it. I believe his was listed as a 5.7 as well. Since ASE and Metric dont play nice with each other I think its just a nice round number. Curious that Corvette did that, being as they are a Chevrolet!!!! :cheers6QTS11OZ said:

Look how Car and Driver has it listed. 346 cu. in., 5665 cc

No matter what, I'll always see the 5.7 as a 350. Because like most, that's all I've known it as and I refuse to change for anyone

Yeah I thought the 5.7 was listed as a 350, then I started seeing 346, 348, etc... so I just wondered the exact displacement. Then I was curious about the 6.0
Thanks everyone.
Thanks everyone.
The old small block chevy based 350/5.7 has a 4.00" bore and a 3.48" stroke, giving it a 350 cubic inch displacement.
The new LSx series engines share only about 3 things with the old small block Chevrolet. They both have 4.4" bore spacing, a 90 degree V configuration and maybe the transmission bellhousing.
Everything else is different. Even the firing order is different.
The LS1 5.7 has a bore of 3.90" and a stroke of 3.62" giving it a 346 ci displacement.
The new "Vortech" truck blocks (4.8/5.3/6.0) and the LS2 share the block design with the LS1. GM has not installed an "small block Chevrolet" style V8 in an American production car since about 2000 or 2001. They still make them for the aftermarket though.
The 4.8 (LR4) has a bore of 3.78" and a stroke of 3.27" giving it a 293 ci displacement.
The 5.3 (LM7) has a bore of 3.78" and a stroke of 3.62" giving it a 325 ci displacement. This engine is most often confused with the old 327 ci V8 used in the 60's and very early 70's. But that is a completely different engine with a 4.00" bore and 3.25" stroke. The 5.3 liter LS4 is an LS2 derivative using the bore and stroke of the 5.3.
The 6.0 has a bore of 4.00" and a stroke of 3.62" giving it a 364 ci displacement. The iron block truck engines (LQ4/LQ9) use the LS1 configuration. The LS2 is an aluminum block evolution using the same bore and stroke as the truck engines.
