Those are my mods so far. I was thinking of bolting on a nice set of heads to really wake the motor up. I figured if i do that might as well swap out to a fast intake system with a larger throttle body too. Im thinking these are the next best steps to take with the motor no???? Im here for advice. Are the Fast intakes pretty good quality and performing intake system? With that said what are a good head alternative for the 5.3 vortec motors??

 

All looks good besides the 3.73's. You run at the track right? What's your 60' time?

 

I can but are season is over for the year here. I have to wait till spring around March to run. I havent made any passes on it with all the new add ons yet it got to late in the year.
