i know i have seen several cam threads but i cannot find much on the 509 purple shafts. i have one sitting on the shelf that i got with a pile of other crap. i hate to be "that guy" but i want to build a motor that just flat sounds nasty. i have heard some sound bites of the 509 and it definitely fits the bill. was leaning toward the mutha thumpa from comp but the 509 still sounds better and i have it already. my question is, what would be a good combination to run with this cam? i was thinking a torqer 2 intake, a 750 holley and maybe a home done polished set of 906's. i would love to get a set of stage 6's but that is not in the cards... or the bank, right now. i know there are better cams and new technology but i have this already and i am going for more of a poser/ head turner than a show nuff power house.
also, what is the lowest stall that will work with this cam?
Check with Mopar Performance as to which converter will work best. I'd estimate a 2600 RPM stall or so. Make sure to get an aftermarket trans cooler, too, just to be on the safe side.
Ditch the Torker 2 - especially with a 383. On a 440 you'll be ok because of the additional torque the 440 produces. A better intake is the Performer RPM but then you get into hood clearance issues with the air cleaner assembly - unless you get the drop base unit from Jegs which workes very well. Better than the Torker II is the original Torker. It will make great power up to 5500 rpm which is great for a 440. A 383 needs to wind up to 6000-6500 to keep up with the 440. If you want another good single plane for a 383 or 440 then get a used Holley Street Dominator. These are very good intakes. Also, good vintage dual plane intakes would include the Edelbrock DP-4B for the 383 and the CH4B for the 440. Both make excellent power (almost as good as the Performer RPM) in the horsepower range you are dealing with.
Next you definitely want headers for max. horsepower. tti makes the absolute best there are IMO. They are expensive but well worth it. A 2.5" diameter exhaust system is the minimum size to use. Mandrel bent pipes are preferrable as is an "X" pipe, however, an H-pipe is acceptable. Mufflers are up to you. Flowmaster, Magnaflow, Dynomax, Thrush all make great selections. Why run stock manifolds if you are going to go with a cam like that? If that is the case just keep the stock intake manifold and carb, too. The car will ruin like crap but will sound like a killer.
Rear gears with that cam should be 3.55 or lower (3.91, 4.10, etc), 3.23's won't suit it too well with that cam unless you have a 440 and a 3200 rpm stall converter.
The Holley 750 is a good carb, no need for anything else.
If you aren't willing to step up and add some goodies to go with that cam then you really shouldn't be using it. Performance is all built on having the proper combination. Sure, it may sound like a Billy Bad *** but it will run like crap.
