Ford 4.6L Modular Stroker Pistons

Forged Pistons Will Pump Up Low and Mid-Range Torque Which Can Help the Modular to be Competitive in Certain Applications

Ford 2 and 4 valve Modular 4.6L engines are extremely abundant having been in production since 1991 and 1993 respectively, fairly inexpensive and can produce excellent power. They are known for their high-revving ability, especially the 4-valve models when modified for racing. 

Now Ross Racing Pistons has increased that performance envelope by offering forged pistons for 3.750˝ stroker crankshafts with 5.850˝-long connecting rods. This increased stroke ( .207˝) will pump up low and mid-range torque which the little Modular really needs to be competitive in certain applications. Ross is offering the pistons in standard and .020Ï oversize bores with two compression ratios: 11.0:1 and a supercharger friendly 9.9:1. Both pistons are designed to handle forced induction or nitrous oxide.

Like all Ross racing pistons they are forged out of 2618 T-61 aerospace aluminum, machined to exacting tolerances on CNC machines that ensure flat ring grooves, precisely placed valve reliefs and dual pin oilers. Other standard features include a second ring land pressure accumulator groove, lock removal indents, pin fitting and radiused valve reliefs. High-strength piston pins and custom ring sets are also available from Ross.
