[QUOTE="Rich Rohrich, post: 114403, member: 16241"] :) The problem or value of the 426 (depending on your perspective) is that, as Brian pointed out it's so good in stock form that the value of "bolt on" parts is fairly limited. To see substantial gains in torque or overall horsepower requires taking the motor apart and working INSIDE :) That said, there are a number of oversize aftermarket pipes that can trade off some of the substantial low/mid range torque for some additional breathing on top. That combined with a Vortex programmable ignition can help him achieve a top end biased powerband that should prove useful in desert racing. The value of the ignition system in the right hands has the biggest potential payoff. [/QUOTE]
