I thought it was a 346, 408 seems to be popular with the new style V8's. If you are wanting to figure up the CI of an engine its

bore X bore X stroke X .7854 X # of cylinders = C.I. for liters take the C.I and multiply it by 16.383 for a rough estimate.

Answer your question?

406 is for the old generation small blocks. It was a stroked 377 with 4.155" Bore and 3.75" Stroke.

And the LS1 is actually 345.9 cid.

That'll give you cc's, not liters....for liters you should multiply by .016383, or do are shinsetsu said then divide by 1000.

Visualize your piston at the top of the cylinder, then at the bottom. The volume of air between these these two extremes, multiplied by the number of cylinders, is what we call the "displacement" of an engine.

Take a stock LS1 for example, the bore (diameter of the piston) is 3.898" and the stroke (the lenght the piston travel from top of cylinder to bottom) is 3.622".

Applying the formula given by shinsetsu (bore x bore x stroke x 0.7854 x number of cylinders) : 3.898 x 3.898 x 3.622 x 0.7854 x 8 = 345.79 cubic inches, or 346ci.

To convert in liters, multiply by 0.016383 like BlueSix said : 345.79ci x 0.016383 = 5.665 liters, or 5.7L.
