Thank you guys for the suggestions. I will call ARP on Monday and see where I get with them. Just seems silly for it to not work? Is there a difference on the pump body between hi volume and a standard pump?
I would guess that ARP when they first made that kit measured everything up and forgot all about the oilpump even existing. Skip forward to the first complaints and someone probably thought it was an anomaly of some kind creating the problem and at that point the whole "we never heard that before" stuck in the vocabulary and if someone mentioned it to engineering,engineering probably said we measured this in the past and its correct and even if it isnt we cant shorten that stud since that would make the threadengagement to short to be optimum and we dont want that to happen.
