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.
