Then it's even less relevant.
A 408 with a fair amount of duration running a hydraulic roller will still have a pretty smooth idle.
For example a 408 with 10.0:1 compression with an AFR 205 head and an OTS hydraulic cam .544/.573 238/248 @.050 will make around 500 HP and 500 ft lbs of torque. Adding the lift from a 1.7 cam might add a few HP...but nothing you'd feel.
