In preperation for the ARP through bolts what is the new hole size suposed to be? I believe that they are 1/2 bolts so I could simply drill out to 1/2 and rechamphur the holes but I just wanted to check to see what other had done.
Thanks David |

Thanks David They should just slip in, no drilling required, at least the ones I got from LN didn't need to be drilled. You won't be able to use the vibration do-dads that go between the case halves. Is this a performance engine? They are not really required on anything but track or big Nickies engines. |

David,
I sold Hencar in Arkansas my old Hoffman Machine 2.0 that was race ready. It is setup with the oversized throughbolts, can't remember if I shipped ARP or Racewear with it. If he hasn't built his fire-breathing Dino burner yet, he can measure and take pictures. Henry is here as well as TheSamba. Good luck, Dave B. |
