I'm looking for cam selection opinions/suggestions.

Truck is an 03' rcsb,4.8/4l80e,3.42.

Goal is 600-650 whp.

I plan to daily this truck and keep the boost turned down most of the time. I typically like a street vehicle to be just a little more aggressive than what most would prefer.

I am in the process of doing supporting mods for an on3 twin turbo kit.

So far I have converted to factory electric fans and done minor cosmetic mods and really just cleaned the truck up quite a bit from the way it was when I bought it. So I haven't really done a whole bunch. I have saved up all the parts required to do the trans swap with the exception of the converter and I'm finding it hard for someone to recommend a converter when you don't know what cam u are going to run. I don't like redoing things and I don't want to spend money on the wrong converter.

I have been researching quite a bit all over about 4.8 cam selections. A lot of guys recommend a z06 cam but I want some lope and something more aggressive.

I was thinking of either a tu1 or tick performance 4.8/5.3 stage 2 turbo cam.

Anyone have any suggestions? Or know of anyone who had a similar combo? I was hoping to make up for the loss in low end power buy using twins. I'm planning to swap to 3.73 gears as well.

I have been running the tu1 cam for years. Its got plenty of torque midrange and still has some lope even with having -2 degrees overlap. 712hp at 12psi. Im upgrading to a tu2 cam so ill have a tu1 available if you would like.
