    What a bummer. Sorry about your engine failure.:(

    Question, have you been able to determine why you lost multiple main bearings? Usually it is due to cavitation, even for a moment. Any clues or pictures? Where the rod big ends blue?

    Cheers!

    although the redline is at 6200 rpm with these engines , it is a big engine, Doesn't do much good on the street to surpass 5500........ It is still a Dodge.... Once you get into the engine and replace the cheap pistons and Valve springs you can then add some RPM. :D

    ^ This is right on... there are ALOT of issues when over revving this engine.

    My shift light is set at 5600 RPM. :rock:

    Flashback in time, Trainman had the very first TB for trucks, its my 2004 RC in the video, see the vents in the front fiberglass fenders....boy this was a long time ago.....watch the very end where I do a mini burn out. Time, 3.09 for Dyno, 3.23 for the burnout.

    The rods are fine and the bearings started to show copper, I think I saved it by shutting it off immediately, as far as why , i don’t know if the oil pump failed or the plunger

    The oil pump in these engines is a gear/rotor type. You would have to have an abrupt mechanical failure of the pumps gear dive to suddenly loose oil pressure enough to hurt the bearings. Dry starts also hurt bearings over time. Even after an oil change with filter, I burp the oiling system by priming before firing.

    The gear/rotor pump will GRADUALLY loose pressure due to lobe and the machined surface the lobes turn within start to wear.

    The big culprit of this style pump is CAVITATION. Cavitation will hurt the bearings in short order.

    Good luck with the new build.

    Cheers

    What do you mean by: I burp the oiling system by priming before firing.

    How do you: I burp the oiling system by priming before firing.


    Thanks,

    How do you eliminate the cavitation issue?
