Yah for only 8 psi with a girdle the block was getting some serious abuse.  I had hoped the block would last longer than it did. about 4 trips to the track And some street driving  |

Was the crank hitting the block also? That sucks! Do you think high rpms crossing the finish line at the strip had anything to do with it, I remember you telling me you were crossing at like 7000 or so. I have heard high rpms is really hard on blocks too. I dont plan on pushing mine near that hard......I have my fingers crossed for mine!!!lol

no bearings are fine even the thrust bearing the caps were moving and that is all i could find wrong no loss in oil press or any thing else |

DING DING DING!!! I just thought of something... Take 1 bolt and stick it through the girdle and put a spacer on it... I am willing to bet the bolt tapers down at that point not securely looking the cap down, alowing it to float around. If you look at the stockbolt, I bet it fits the top part of the cap real tight, then tappers down after like 1/2 inch or so....  Let me know what you find.... |

Not the cause; the bolts just hold down the caps the notch in the block holds the side to side movement interesting thought anyway  maybe it was the first dyno pass that caused the caps to move 20+ psi 619whp @4500  ....maybe Wastegate was too small, Now got twin 50mm gates will hold 2psi all day  Just going to spend the money  and Put a DART block in and crank the boost up going for 1000 fwhp |

Yes I Understand, however it appears to be moving back and forth. I would have to see the bolt to be sure... They may not be intended for use with spacer and a stud girdle... you may have to swith to studs or something else... It may also help to tack those spacer to the girdle. the more things you stack up the more likely it is for the bottom part to move around... just my thought on your issue. may be it will help and you will be able to get back out there and play for a little while before you have to poney up the big bucks.... |

Hell yeah! I had similar issue w/ the mains on my 4 bolt 388. But my problem was enuff for the rods to gouge in the block near mains. Ends up the Milodon studs I used weren't all concentric. Straight but off center. So after they were installed, the torque changed and the end was just a matter of time. |

The 2.75" mains will be good for the RPMs you are turning too.
