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)


69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight
418 BPE factory replacement headed stroker, 565 lift solid cam
Best so far, 10.40 @127 1/4
1.41 best 60 foot
6.60 at 103.90 1/8

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.
