Modern Hemis are not quiet, I'm not talking about exhaust. These modern power plants, seem noisy to this old school guy. My ford 08 F150 5.4 drove me crazy, between the three manifod replacements from leaks, and the phasers , and 6 ft timing chain slap, valve tensioners, drove me insane. Traded it for my currant 6.4. when it had 120k. Someome is still reporting car fax maintenance ,and to this day, I get notifications from them, why I do not know . But the current owner is at 175K, miles with routine Maint. He must be Deaf, or ignorant, or lucky. Edit: maybe i was paraniod!
