gonna guess it should make a " real" 475 horsepower.

I had a similar 416 but with stage two ported eddies and a somewhat bigger flat tappet that made just a touch over 500.

Should go low-mid 11's if the car isnt real heavy( 3300-3400 pounds it should run in that range)

I'm guestimatin' 450-460 if the heads are stock. Ported (decent job), I'd put it up around 475-490.

Should be right where these guys are saying. I would guess 450-475 on my dyno. Which type of dyno are you testing on?

Tried to post a link,but couldn't. Go to the search at the top of the page and type in Hughes based 426 dyno test. I tested a 4.03 X 4.180 with stock Edelbrock heads to give you an idea.

The heads were right out of the box.
It was run on a Superflo Dyno.
