Some questions that need to be answered first; what is the torque converter stall now, or are you willing to have one built? What heads are on the motor? What is the compression ratio? Intake manifold and carb ? What is the rear gear ratio and weight of the car? Exhaust system discription? What type of cam do you want, hydraulic,solid, flat tappet or roller? Being a driver, what kind of highway speeds and distances is the car used for?

Being a driver, what kind of highway speeds and distances is the car used for? ....and, exactly what do you want from the car. I have a friend that has a 500 inch BBM and although performance was important, his priorities were low maintenance, easy on parts, and to sound bad azz. His Scott Brown cam gave him EXACTLY what he wanted. It is a low lift, soft ramp hydraulic FT, with 320° advertised duration. Probably giving up 50 hp in cam choice alone, but he could not be happier, and it is truly about the most bad azz sounding car I've ever been around.

Ok, i guess i should have given a little more engine specs to start with 383,,,stroked to 496 lunati hyd cam,,494 513 eddy intake dual plane eddy 650 carb 10 plus compression 440 source aluminum head otb 2800 stall convertor 1 7/8 " headers 3" exhaust out the back 323 pos rear,,,
Car sounded real tuff when it was the stock 383 engine, and ran good also, now that it has been stroked, it's very docile, and doesn't have the overall power it had before, I am thinking it need more cam, and carb, was just trying to figure out what camshaft I need to go to, to get the car back to sounding good and running good, this will be a weekend driver, not a race car,,,

If you like the Lunati cams, it looks like the next one up would be a good choice for your combo. #10230704. 276/284 adv. 234/242 @ .050. .513/.533 lift. They recommend an 850 carb, which we already knew you needed. But they also recommend a 3.73 gear. You might get away with it with the stroker motor, though. Your compression, converter, and intake look good.

Big C.I. motors need bigger cams than the smaller C.I. motors with the same parts need On your deal I would look at Comp Cams Extreme lift High Energy series and use either the XE285HL or maybe the bigger XE295HL grind for the nastier rumpty rump sound at idle I have that grind in one of my mild 464 C.I. pump gas motors, I installed it four degrees advanced on the intake lobe and it sounds really impressive and ran real well in my old 3450 lbs. Duster The XE285HL might be a better choice for your deal though, my Duster had a custom built ten inch converter and 4.10 gears with three inch exhaust to the rear bumper

........and doesn't have the overall power it had before..
If your stock 383 had more power than the 500 inch motor with the same cam, you need to looking for other problems first.

If the stealth heads still have the as supplied springs, and you're looking to be able to reuse them, I'd suggest a Howard's Rattler 728081-09. The mp 509 would also be a good choice, although recently I saw those priced in la-la land, so I'm not sure those are a cost effective option any longer(unless the price has come back down to something reasonable).
Edit: I just did a search...... This past summer the 509 cam kit was around $500+. Looks like they have come back to their sanity....... Summit shows it for $299.

Also, the "Ede dual plane" could be either a std Performer, or Performer RPM. The std Performer is too small for a 496, as is the carb.

RPM + 2" divided spacer if you have the room.
