4.6 Pistons specs

[Curt Hunter <amy_curt@pacbell.net>]

Pistons

Both engine derivatives have new lightweight pistons with crown height reduced
from 48mm to 36mm. The small end diameter has been increased from 22.2mm to
24mm to withstand the higher loads from the increased performance.

Connecting Rods

The engines are now fitted with new con-rods which have been designed to
reduce vibration. They are also fully balanced individually.
