Overview

The ATK HP08 is a 302 cubic inch (5.0L) Ford small block engine assembly designed for performance applications. It delivers 375 horsepower and 380 lb-ft of torque. The engine features a seasoned OE Roller Block from 1987-1995, a 4.040 x 3.000 bore/stroke, and a 1-piece rear main seal crankshaft with 50oz external balance. Internally, it utilizes OE rods, hypereutectic pistons for a 9.5:1 compression ratio, and moly rings. The camshaft is a hydraulic roller with specs of 220/224 @50, .512in/.512ex lift, and a 112LSA, paired with a double roller timing chain. Airflow is managed by ATK HP aluminum cylinder heads with 58cc combustion chambers, 185cc intake runners, and 2.02/1.60 valves, actuated by aluminum 1.6 roller rockers. It comes with a Fox Body (Mustang Dual Sump) oil pan and a Melling high-volume oil pump.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
