Often times companies will put a "name" on a size of a motor, but it isn't always the most accurate. This is one example.Originally Posted by SX-MAN
5.0 * 61.02 = 305 they are both 305 ci.... the crank makes the diff...........
GM used the 5.7L V8 for decades. It was always a 350ci motor. But when the LS1 came out, the displacement actually went down to 346ci.....however, it was still called a 5.7L.
My motor is peculiar in that it's the exact opposite. Mine is a 7.0L, which comes out to 428ci. However, since GM was known for its 427 motor, they just CALL the LS7 a 427 (even in the car's literature), even though it actually IS a 428.
