I don't know Bob you might have actually have under-rated your 440. I had one of those on again off again old customers of mine come by the shop yesterday (you know the type..... after he can't figure it out or find some one to fix it for free he'll finally bite the bullet and pay shop rate all the way).

According to him his (STOCK) 440 Magnum (which it really is) is making 500 HP of course he "believes in balancing and blueprinting all his engines". He's even thinking about putting on "them aluminum heads" to get 700 HP out of it

It's so nice to tell people I'm semi retired and send them somewhere else.
