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

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.

ARP are 3/8" and drop right in.
