Im putting splayed four bolt mains on my block with ARPs. What do I do about the stud bolts that are supposed to hold the windage tray? Do you just use the old bolts or can you order special ARP studs? thanks

 

Yep you need the windage tray or a pan with a windage tray in it like a Canton pan. It can cause a lot of issues and you can run the pump dry and spin a bearing. OUCH!

You can call ARP and ask them for the center studs that hold the windage tray. You need anywhere from 5-6 depending on the tray.

5 or 6? There are only 3 that hold on the LT1 windage tray right? Anyone else had any experience with this. I want to keep the stock pan... No more money....

 

Just get 3 from them then. You could always get a Milodon Diamond Screen tray and trim it to fit the motor. Those need 6 studs.

I ran into the same problem with my splayed mains. I'm running the Milodon 7 quart pan without any windage tray. I figured that with 7 quart I shouldn't dryout the sump. I'm probably losing a slight amount of HP due to oil wrap on the crank though.
