Drove GM 8.1 liter engine over 150,000 miles in two coaches, always made the top of the hill. Could not keep up with my old Corvette from the line, or even with my RAV4, but it got out into traffic just fine with a little planning and patience.
Got me a diesel for my 3rd coach, Cummins ISC 380 HP. It is no faster off the line than the gassers - lots more weight. And so far it has made every grade I've tried. My son, who lives up in a holler on a mountain dirt road says he can tell the difference because he can't hear the engine roaring from 1/2 mile off like he could with the gas engines. My biggest expectation is longer life, my last coach had 110,000 miles on it and needed the interior rebuilt from use. Wouldn't put the $$ into the coach because I had used half or more of the expected life of the driveline. New gasser would have been fine but I wanted a diesel and DW found an acceptable floorplan in the diesel. I got the engine and drive line I WANTED and she got the living quarters she wanted.
