Geeto67 Posted November 1, 2015 Report Share Posted November 1, 2015 4.8 will take more abuse than a 5.3. That's really interesting, I wonder why? Better components? Shorter stroke? Quote Link to comment Share on other sites More sharing options...
DTM Brian Posted November 1, 2015 Report Share Posted November 1, 2015 That's really interesting, I wonder why? Better components? Shorter stroke? The less rotating mass the better Quote Link to comment Share on other sites More sharing options...
coltboostin Posted November 1, 2015 Author Report Share Posted November 1, 2015 That's really interesting, I wonder why? Better components? Shorter stroke? Less stroke=less force intot the rod. Also the 4.8's have massive first ring lands. You need to rev them higher to get the max HP, but its eaiser on the rod to make 1000hp our of a 4.8 than 900hp on a 6.0. (considering the application in loan of ft/lbs over rpm) Quote Link to comment Share on other sites More sharing options...
