no stock cubed stock ported head nitrous motor needs more than 245 or 650 lift.
assuming the car has a 90mm intake or ls6 and at least a 200 shot. id go 234 250 620 620 lift and 114 lsa... might need to advance it 2 degrees on a ls6. I will also guess not to many will go out on the limb to suggest a cam . and the magic stick would not be a good nitrous cam.

it doesnt matter, look at his screen name.lol
so something huge by large with a wide lsa... big nitrous tends to like alot of exhaust duration so a nice spit would be good and a wider lsa. 114ish will probably be the widest you find in something that big

good attention to detail, lol, so would i be looking for something like a 235/245, or 235/240? how much more exhaust duration? like 5-10? im using 1-3/4 headers if that plays a role. i heard it does

Intake design plays more of a role in camshaft selection than headers. my cam works really well with traditional LS intake than say a single plane. Bigger isn't always better.
Here is my cam 237/243 .597 .617 112+4
You won't find it on any web store though
It does pretty well on a bigger shot.

Your best bet is to have something cut.
If you keep the lift down, the valvetrain will thank you.
If this is a h/c motor stock bottom end, I'd try someting like a 238/248 with a 115 lsa, advance it a degree or 2 as well...and keep the lift in the 580 to 600 range. Heads and intake won't flow any more after that in the lift department, going a ton past that will only cause uneeded wear IMO.

We rearly use anything of the shelf . I have ground 10 nitrous cams this summer for guys already.every setup needs something a little different. If you only have relifs we would rpobably have to shorten it up some.....

with small headers and stock ls6 ported you will need more than a 5 degree split on a 250 shot .... 10-12 or else its not worth changing. 630 lift is fine we run more with stock rockers no problem. but you might not have the room on the exhaus side with bigger valves. how much did you cut for the reliefs? what thickness gaskets? what size valves?
