Which camshaft
Just bought a vette that has an unknown camshaft in it. It's an LS3, full exhaust(headers back, no cats, no mufflers) and a K&N cold air. She's a weekend warrior, I don't care about mileage or anything. What kind of cam is a pretty aggressive one? Dyno on the car as is shows 438, like to see that number closer to 450 or higher lol.

$500 is not bank breaking but I would do everything once and be done. If you ant heads, get the heads and supporting cam now. But that's me and I understand if that's not you.
Good luck, let us know which way you go.

I was in your shoes a few months back. Was going to just do cam and bolt ons. My new, to me, 2013 M6 coupe had 50K miles on it when I bought it. After thinking about it a bit, I decided I needed to change the lifters. Had no idea how well the previous owner maintained it. To swap lifters, you have to pull the heads. I wouldn't put stock heads back on without a valve job and a clean up pass on the head decks. That would cost several hundred bucks at any machine shop. Tx Speed offers a program where they CNC port your heads, do a valve job, mill to your specification, and assemble them for $750. I sent them a set of Brian Tooley .660 lift springs for them to install on my heads. When I got them back, they looked new.
Here's everything I did to my Vette with the results: https://www.corvetteforum.com/forums...cam-build.html
The camshaft I used may not be as rowdy as you'd like. I specced it for drivability and power. I wasn't willing to give up a whole lot of drivability for a few extra HP above 5500 rpm. I've already had my last crappy driving camshaft.
