How do think this cam will behave in 408 ?

My 414 has a Comp 242/250, 106/106 oval track cam, iron heads, Air Gap. Makes torque everywhere. I run a stick with 3.55 gears. No need to downshift, I just floor it. Pulls very hard from my cruise rpm of 2600@60 but is done at 5400. Car is a '71 Duster. I'd go bigger cam than 22*@.050.
