Here is the combo, I am building this engine for a street driven cuda, but sometimes will see a 1/4 mile pass or two. Mainly after torque and a working rpm range up through 6500rpm.
The combo so far is a fully prepped 383 block with a 440 source 431 kit going in it, stealth heads out of the box, preformer RPM intake, 750 cfm Edelbrock carb, headers and a 3.55 out back running on pump gas. I looked at an isky cam kit number 165128, but am wondering if there is something better for the power I'm after.

Stick or auto,how high stall

auto, 3000 stall 11" hughes

The Isky is an old school cam (slow ramps). .465 lift isn't going to maximize the potential of the stealth heads. You could do much better, but you'll need to ensure you have piston to valve clearance.
Your carb could be improved upon too.....

so I am looking for recommendations, what would you run, I have about 1" piston to valve clearance.

The good old MP 528 cam would work with your basic combo,what rockers do you have?

I'm building one myself, albeit quite different with a more performance-minded combination, nonetheless important areas to carefully consider are the oil system (1/2" npt internal pick-up, higher capacity oil pan w/tray and the std volume pump will do fine, as-long-as the flow isn't hindered), an adequate exhaust and fuel system. As for cam choice, the 284x.528" MP stick is a decent choice, however...if you're looking for something more in line with your engine combination and a hyd grind, call Kirk (or one of the other guys) at Bullet cams and discuss it with them. One thing for certain, the quality of the machine work is critical in the performance and longevity so don't scrimp. Don't get excess on sizing or choke it down and that engine should perform quite well.

a new set of SS440-1 cats, that I will machine the ends so they don't push on the retainers.

what is the rpm range on the MP284/528?
