Our giveaway GM Performance Parts 502 Rat falls in between our mild and wild big-block combos. With McKenzie pocket ported GM Performance Parts rectangle-port heads and a dual-plane intake, this Rat made 608 lb-ft for torque at 4,000 and 553 hp using the 502/502 hydraulic-roller cam. By the time you read this, Brain Hoverson of Bloomington, Minnesota, should have that fat Rat sitting in his garage. Congratulations, Brian. It pays to read Chevy High! View Related Article
