    I would have fired her up today, but I broke a 45* XRP fitting on the water feed system, already ordered from CP Performance.

    Tahiti Boss,

    I got it from Junior at Mondello's, It is nice and compact, good quality and is very easy to install. The fan belt is also quite short, no vibrations and it is nicely tucked away.

    Looks real good! I hope it performes as well as it looks!

    The guage for water pressure is a bit to high of pressure no. about 30 to 40 max I would think would be better! JMO! I may be looking at it wrong!

    That should be the talk of South Africa for sure! WT

    The gauge is Kpa, and I run it at 90Kpa - about 15 PSI if i remember correctly.

    It has been exactly 12 months ago that the motor spun a rod bearing. I have done research on the Olds engines for a solid year. I implemented a lot of stuff and advice that I got from the PBF forums and some more.

    I have experimented with different set ups and combinations, did a lot of testing on my test engine and came to a couple of conclusions on Olds engines.

    1. Get the oiling system sorted. - drain backs from the heads, mods to the crank, restricters, correct oil pump and pick up and most important, fit an oil cooler .

    2. Use marine grade gaskets.

    3. Correct bearing clearances.

    4. Forged pistons with Nascar I beam rods.(slotted on both sides.)

    5. Balance the rotating assembly.

    6. ARP fasteners. - Rods, mains and heads

    7. Correct valve geometry.

    8. Measure and check your machinists work five times and check everything again.

    . One last thing,"If you are not a praying man, an Olds will certainly make you start praying. "

    Just my opinion.
