Enginetech P30138060 Dish Top Hypereutectic Piston Ford 7.5L 460 .060 Oversize

The Enginetech P30138060 is a dish top hypereutectic replacement piston for the Ford 7.5L (460 cubic inch) big block V8 engine, machined to a .060" (1.50mm) oversize bore diameter of 4.420" for use in engines that have been bored beyond standard size. This piston is designed to meet or exceed original equipment specifications, delivering reliable performance in engine rebuild applications.

Key Features:

• Hypereutectic aluminum alloy construction for greater strength, improved scuff and seizure resistance, and superior groove wear compared to standard cast pistons
• Dish top crown with two valve reliefs, matching the OEM combustion chamber profile of the Ford 460 V8
• .060" oversize (4.420" bore diameter) — engineered for blocks bored +.060" over standard
• Coated skirt reduces friction and wear, helping extend piston and cylinder wall life
• Superior size and weight grading within each set for improved engine balance
• Pistons are decked 0.010" to 0.020" with principal diameter sized to compensate for the oversized bore
• Machined oil return slots are chamfered to prevent stress cracking
• Includes provisions for oil distribution to the pin bore to prevent pin starvation — a leading cause of engine failure

Enginetech pistons are manufactured using state-of-the-art materials and processes to match OE requirements. This piston is sold individually.
