hey guys, i've been trying to find the factory cam specs for my 07 silverado gmt900 and i haven't had any luck.

does anyone know what the factory specs are? i'm playing with the idea of throwing on some rocker arms.

also how hard is it to swap the gears out in the rear axle? i think it's a 10 bolt 8.65in. it's got the cr@ppy factory 3.23s and LSD in it. i already have a 3.73 gear set for it. i'm just trying to figure out if it's something a wanna do in the parking lot of my apartment (can't wait until i can move into a house again).

thanks

 

Dont do the rocker swap its not good imo to mess with the geometry of LS engines rockers. They're already 1.7 from the factory so Id swap a cam if you want more engine.

As for the gears? Its a bit tricky to swap em. I wouldnt recommend that as a driveway job. Without a GOOD powerful impact gun and lots of air its very hard to set pinion pre load plus you'll need a press etc for bearing installation. Its pretty involved but once you have all the nec tools its not so bad

 

Sound advice there^
