I am going to have a machine shop install splayed 4 bolt main caps for my 2 bolt Lt1 block. I guess they are going to need a bolt kit for this so I was going to get arp stud kits. But first I have no idea what a windage tray is and from what I have read I think certain studs can hit the windage tray. Can I get a arp splayed 4 bolt main stud kit that will work with my windage tray with my LT1 engine? Also does anyone know what the part number would be? Thanks for any help.
