During research and development, the 5.7L Hemi was run full load at peak hp for 300 hrs. Nothing melted or broke and tear down revealed normal wear. Why would you rpmaphobes think it's ok to run a diesel at 2500 all day long which I did with my '98 towing or not yet it's eminent destruction to run a gas engine at 5300 rpm all day? What makes 2500 rpm or even 2000 rpm low in you mind?
300 hrs is a long cry from 9000 hrs.
Maybe they should have tested it for 301 hrs.
My '03 Hemi 2500 broke a valve spring with a little over 105,000 miles in '09.
Goodbye hemi, hello Chevy 6.0.
