Cam recommendation There is a lot of information here and I'm new to the LS family. I'm still trying to learn the ins and outs of cams but I am building a 6.2 out of an LQ4 with L92 bottom end and (as of now) ls2 top end. Its a daily driver stock drivetrain Trailblazer SS, I'm looking for a bit of power adage but also dont want to fight it at low RPMs. What kind of things should I look for? Again, I'm new and learning so bear with me haha thanks in advance!

So basically you running the trailblazer SS intake with stock 243 cathedral heads on a 376ci ?
Plenty of questions come to mind as I'm about to go into work. Maybe another good member pick up where I left off.....
Do you plan on running a stall?
Do you always plan on keeping it naturally aspirated?
is you running aftermarket headers? If not you'll need more exhaust duration than normal to help get the air out the motor.

I'd look for IVC in the 40-43 degree range, EVO in the 50-55 range and "negative" overlap to avoid fighting it as well as being easy to boost later.
So, let's say IVC 42, IVO -2, EVC 0, EVO 54
220/232-114+3. Something close to that would likely give you a good blend of your goals
