Engine that's been sitting

No one knows the arp part number for the main studs?

I emailed arp and they don't have a listing for the aaz. Does anyone have any main bolts on hand they could grab some measurements for me? Arp gave me this form and they can see if they have any compatible kits...

AAZ uses the same studs as the AHU/1Z; it's the same block.

Thanks! I was looking for alh studs but couldn't find a number either, didn't think to search for ahu.
http://arp-bolts.com/kits/ARPkit-detail.php?RecordID=1190 should be the correct kit then? Is there any issues with them if my engine originally had the shorter main bolts?

Oh good question. I really don't know for sure! The bolt holes are PROBABLY sufficiently deep - it's not like there's any significant difference in machining time to cut the threads all the way during manufacturing. If it were me I'd buy the studs and go for it - worst case is you can't use em and you need to sell them - essentially unused ARP stuff is worth 90% of its original retail price. I know I'm going to be looking for a set in not too long.

So I can only find 30mm oil pumps locally.  Partsplaceinc lists a aftermarket 36mm pump for $50 and an oem for $139.  Anyone have any input on the quality of the aftermarket?

In case anyone was wondering "hans pries topran Germany" 100 310 756 or 028 115 105g pumps are 30mm
