ARP main stud kit for small-block Chevy described as a splayed configuration and supplied for use with a windage tray. The splayed-main design and the windage-tray compatibility are stated to match specific SB Chevy block builds where wider main stud spacing and an oil-control tray are present, giving a tailored main stud solution for those setups.
