Whatsup yall. about to supercharge my second 4.0 after my last one caught on fire from a melted fuel line. i need to pull my engine to repair the rear timing chain tensioner, and while i was in there i was gonna replace my head gasket, studs, and timing chain. does anybody have any experience in running these engines hard? i wasnt going to even touch the bottom end at all and im not sure if it will hold up at sustained high rpm. any advice is appreciated for upgrades or maintenance so i wont have to pull the engine again soon!
