Installation summary

This expert-level installation requires professional mechanics with advanced engine building experience, specialized precision measuring tools, and a lift to drop the front subframe for oil pan removal. Technicians must meticulously verify and record oil clearances using precision micrometers and plastigauge to ensure the ARP connecting rod bolts are torqued correctly with the supplied lubricant. Particular attention must be paid to maintaining absolute cleanliness and proper bearing shell orientation during assembly to prevent catastrophic engine failure. Due to the extreme complexity of accessing the rotating assembly and the critical precision required for bearing clearance, professional installation is strongly recommended.
