Just because you need emissions & use an emmissions legal cam doesn't mean it will pass. The cam is all wrong for that set-up. I made 390 H.P./362 TQ. from a 337 stroker recently with a 4 bbl carb. And a dual plane intake. It doesn't pass emissions but it sure runs good. Talk to one of the cam grinders and see if they have something that will work. Without compromising your h.p. & torque. If your spending the money for the stroker what's a couple of hundred bucks more for a cam that will work for you.
