Cam my 416

Hey. Looking for help or even approval of a cam my machine shop guy and I picked out for my 416 stroker.

We ended up picking on a Comp cam purple flat tapet, part number 20-671-4. 484,484-239, 246.

Purpose of this motor is streetable. Going into a 72 Duster, disc brakes all the way round with booster, reared gears 3:55 true tracs. I think compression closer to mid to high 9s. Pump gas.

I hear these strokes are good for 500HP but I'm happy with a sleeper 425HP. I was wondering if this cam is perfect or do I need to bump it up a tad. Just don't want a lopey car that I can't keep running at stop lights and is not a pooch.

Thanks in advance
Foo
