Hi All.
I am new and looking at acquiring a 3500 Express with diesels. I am interested in the difference in fuel burn (mpg) between the 370 hp (6BTA5.9) and 450 hp (6CTA8.3) Cummins. I found one thread indicating 1.2 mpg for the 370s and wonder how the 450s compare? Based on Cummins curves, the 450 is much higher at comparable RPM which makes sense but I am really interested in mpg. Any information, wisdom etc. would be welcome regarding the 2 engines. This looks like a great forum with a wealth of information.
Thanks!
