alot of good info. thanks guys.
i love the way the stall is driving now. i really dont want to swap it out. and im still debating doing nitrous. honestly dont know if i will or not. i do want to make sure i have the correct cam and setup before i spray which is why i want to figure this out.

My vigilante 3200 drove great also. But i made the swap to the 4000 stall. Honestly, it drove just as good as the 3200 and pulled harder.. I mean pulled insane. So if your looking to changing out something i would do the stall or just add the spray. I was gonna swap out my reverse split for something bigger because it drove so easily, i could have went bigger. But just the performance i got out the bigger stall i would have kept the cam, threw on some heads, and spray. So my setup would have been like yours. So go with the bigger stall, and/or add spray.

There are many variables that affect your choice of cams. Main difference between a 5.7L and a 6.0L is the bore size.
With added cubes, the 6.0 will allow a bit later IVC (intake valve closing) than on a 5.7L without loosing too much low end grunt.
Typically for street the 5.7L likes a 42 or 43 IVC. On a 6.0 you can do a later IVC as long as you keep it under 50. This of course is relative to heads, intake etc... that you'll be running and power band desired.
What I have found helpful in choosing cams is one has to be honest about the purpose and powerband desired. Most just say I want XXX horsepower. But in reality one should answer "where in the rpms do I want that power?". A 400 hp autoX car has different powerband requirement than a drag car.

Spray it and see how you like it. Then if you think its too slow go for a cam change. Eventually that baby converter is gonna be the limiting factor anyway. As is the car is in the 11's with a 100 shot of gas you will really be moving. Like you said cam plus springs and the time/money spent will pick up some power. But when its all said and done the nitrous will net you more power for less money.

I went from a 3200 to a 4000 and i was glad to keep my reverse split in there. The stall made a huge difference.
So you will go with the bigger cam and be stuck with a small converter..
