Default LS3 416 cam selection advice

I'm doing a stroker conversion to my LS3 bringing it to 416 cu/in. I was told a bigger cam would compliment this upgrade and was wondering if anyone had any advice/input on a good cam to go with. The cam that was in there previously was a 231/237 617/607 112 it has a noticeable cam idle and would like it to stay that way.....any help would be appreciated. Thanks

What are you doing for heads?

Also, manual car or auto?
What stall?
What gears?
What kind of car?

Stock gear in a 5th gen auto is a 3.27. Sticking with a 3200 stall is going to limit how big of a cam you can go with. With a smaller stall like that and a big rowdy cam, you'll experience cam buck and surging.

I thought the one I already have was pretty stout, maybe for a stock bottom end it is don't know. I'm not necessarily looking for a big roudy cam, was just going to stay with what I have but was told that with more cubes it would make my cam "smaller" and that I should get one that compliments the bigger displacement. I know there are ALOT of variables trying to select a cam, I was just looking to see if anyone has any first hand experience and found something they liked. If not I'll just stick with what I have, with the stock bottom she's already putting out a touch over 500 rwhp so I'm sure with the stroker improvement alone it will be more fun to drive.....

How big was the engine that cam went with previously? 231/239 .625/.626 111 LSA would make power all the way to 7K rpms. If you want driveability without the bucking, go with a longer LSA to tame it a bit without turning it into a turd.

231/237 617/607 112 that's what I have right now and it pulls quick and hard to 7k, nothing wrong with it and it's very drivable just wonderin if I should upgrade now while it's all apart.

You could probably stick with what you have now on the intake side and go a little longer on the exhaust side with higher lift to hold the power up top. I am running a 223/235 .625/.626 112 on a 403 stroker and it starts to lose power at 6600 but gets off the line quick and has great mid range power. I'll be upgrading to that cam I mentioned before once it becomes a 1/4 mile car.

I'd contact someone like Martin Smallwood or Brian Tooley and get their opinions, they are the professionals.
