I was wondering that myself and the calculations work out to 5.7L=350 cu. in. more or less.

What got me to the calculations was trying to make a comparison to other vehicles I drove. The first car I ever drove was a '76 Buick Century (the one with the ugly front end) with a 350 V8. It was rated somewhere in the vicinity of 200 HP and got 12 MPG on a good day. My '09 Ram with the 5.7L Hemi is almost double the HP and I'm averaging 16-17 MPG overall and 20+ on the highway. Engine technology sure has come a along way.
