    If you run a stroker, that will resolve the issue of not having to rev it as hard. I also run a 6 inch rod and DSS Forged 383 pistons. Pistons are lighter and less side loading from the longer rod. That may help you as well.

    hi
    Even the Holden v8 is suffering now corrosion issues .
    I know sonic testing is not full proof but get some one experienced in there use and it will at least give u confidence on the bore thickness ,

    Almost every time I have done welsch plug leaks I remove the engine and pressure clean the water galleries . Engines with way less years than holden v8 I get at least 1-2 cup fulls of rust !!! Remember this all goes in the radiator ..

    Just as a learning exercise smitty....is there any sign of detonation on the rod bearings.

    Horror story I know but this opens the door to better things...

    You may still have the same problem. The cooling system mod HDT did was trial and error. It wasn’t the cooling system causing there head gasket failures..

    I made a number of changes (not only cooling system) and went from doing 2 or 3 head gaskets a year to
    none zero zilch in the past 2 1/2 years. The head gaskets, when i pulled both heads, are fine. Neither have failed

    Scat 3.48" Chev journal, 6" scat pro sport I beam rods and piston to suit (JE or SRP) as per TK thread, lighter combo than holden journal set up. Leave H beam rod for blown engines. SFT or hydro roller cam and let it sing. Maybe upgrade the mains to 1/2" as per TK thread as well.

    sell your ass on the streets of melbourne for 50 cents a hit (haha) until you save the cash for a TP little paw block do away with the old flogged out holden castings that'll likely only fail on you again thus you'll be back here with yet more pics of another pile of busted parts

    if you add your old busted motor, this busted motor an the next one you'll throw your hard earned at (an maybe the one after this) you could of had/have a new foundation(block) that wouldn't of cost you so much of a headache, disappointment, time an money........
    HOLDENS don't leak oil, they simply mark there territory! like a dog p!ssing on a tree

    It was partial detonation from the change of locally allowed avgas to pump fuel under the European regs.
