With the 918's being the bottleneck of using more aggressive higher list cams, I would suggest maybe something like a torque 2, F13, or something along those lines.
The XFI/LSX stuff is out the door unless you change springs.
Texas speed sells the Torque 2 which is a 232/234 duration with right at 605 lift.
The F13 is very similar as far as specs go and Futural sells this cam.
Take a look around. I have used a 228/232 cam quite a few times with great results.
Good luck.

Well bottleneck as in weak link in your valvetrain IF you were to try and use a faster ramp rate camshaft. Especially something on the LSK lobes. The springs are only rated to 600 lift however I have seen cam's that are 610-615 work with 918's. Not something I would suggest but something that I have seen work.
I personially would switch over to a dual spring kit like the Patroit dual's if I was running anykind of aggressive camshaft. Their springs kit is awsome and is just added insurance. Even if I were running a cam with 590 lift I would perfer the Patroit kit. The cost isn't much but the value is huge. Check them out of your not fimilar with them. They are a sponsor on this site.
Anyways I am not trying to get you to change your whole setup especially if you already have the 918's installed, but if your trying to get into a peak HP cam only setup then the 918's might not be the best choice.

He means the 918 springs are limiting your cam selection since they are only good to .600 lift.
If you wanna stick with the 918 I'd personally go with a 224 cam. It's not super big, but when you addd some heads with it you'll be over 400 RWHP. Not to mention your under the curve power is gonna be great. This means you won't have to spin the motor as high to get your peak HP. This is great for helpin the stock short block last longer while making great power.
Alot of people under estimate the smaller cams, but they have sent several full weight vechicles into the mid to deep 11's on motor. Peak HP is not always what its about, its also about how you get there. If you wanna go bigger your gonna have to look into a better spring kit & possibly some other mods to go along with it. Just some food for thought.

Big Mike makes some great points. I am assuming your looking for the biggest most peak HP cam out there based on you saying its not your daily driver.
But if your just looking for a nice sounding cam that will add some good power throughout the power band then the 918's can work great.
The cam he suggested is a 224/224 typicially a TR cam, but I believe everyone knows this cam. It has been very popular for years and years and years. What exactly are you looking for out of adding a cam?

Get a 224/224 .581/.581 112 from TSP then. It'll work perfect with your springs & the 112 LAS will give you the lope. This cam make solid power through the entire power band, not only top end.
