A steel crank, stock or aftermarket rods would be fine (you can even do with a cast crank but with so many steels out there why?), obviously aftermarket rods would be better but you should be fine with stock reconditioned, and a good set of forged pistons.
With open headers it will probably pull to about 6500 rpm. Probably in the 530-550 horse zone, it will run well. Alot of people will tell you stay away from the old DC509 and like it will be said theres better cams but it will make power. Maybe look at the .557 as an alternative without much downside for street manners but more power potential. With the 509 you'll probably want about 10-10.5 to 1 compression with the Eddy heads.
What do you want to do. Alot of people will probably come on and tell you that you need 12:1 compression, 4.10s, and 3500 stall for it and while it will perform better set up like this alot of 509 cams have been used on the street. Id look at other cams though simply because the Eddy heads would make more power with more lift. The DC cams are based more on racing with factory heads.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

John, you know how that goes... In any case, the original .509 is not a streetable cam for 75% of those that run it and actually get one installed where it's designed to be... (i think the lobes are fine.. if they could just get them in the right spot!!)
I'd use the Comp Magnum 292. It's quieter than the XE line, easier on springs, and will live a bit better on the street. If you have power brakes, the XE274H would be my first choice for you.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Run a new cam, the 509 is outdated. MP is prone to having soft lobe junk made anyway.
Have any PROOF to back up that statement ?
yeah put a 509 cam in a 8.75:1 440 w/ logs, a dual plane intake say a holley 750 vacuum carb, 2200 stall and 3.23's and you'll get a DOG. It's not a cam designed for the street. It doesn't make any power until you get the rpms up. Same goes for the 484. Don't make me google the MOPAR engine builders guide circa 1980.
If you have good compression, good heads, good exhaust, 3000+ stall and some gear it's a nice cam.

There is nothing wrong with the 509 or any of the old Mopar grinds.They work really well.
