Cam newbie

[Ranger175]

I have a 2013 ZL1. I currently have Kooks LTs (catless) and Roto CAI. Wanting to upgrade cam. Do I need to upgrade any pulleys or will boost levels remain relatively OK with just doing a cam and tune? Also, the car has ~9500 miles on it. Will keeping my stock lifters be OK?

On a side note, my goal as of now isn't to get too crazy with the car. It's a weekend warrior. I would like to eventually be between 600-650 so I'm sure pulleys will eventually be in the future. I was just trying to hold off on having to buy/add heat soak mods such as upgraded heat exchangers at this point in time (limited money). My ideal cam would provide good/noticable lope at idle but still maintain great drivability, good power, and low engine/drivetrain abuse (if that's possible). I've read ALOT of threads on the forum on this topic trying to educate myself and was appreciating ideas from you experienced ZL1 guys with regards to my goals. Thanks in advance.

I would recommend installing an ATI balancer while you're in there to save time/labor. You can buy a stock size or 5% blower ring and swap to a bigger one later on with ease instead of having to pull the stock balancer back off down the road. If you want 650rwhp, I'd say go with the 10' blower ring on an ATI balancer if you never plan on changing the upper pulley. Just be sure to add at least 850cc injectors and consider the $530 Ron Davis heat exchanger.
