5.3- Need some good advice

My truck is a 2001 gmc sierra 1500 Z71. current upgrades include spectre
CAI, Taylor Cable TBS, Pacesetter shorties (uneducated purchase), Flowmaster 40 series muffler, and a bullydog programmer (another dumb purchase), 4.5" suspension lift and 305/70/r16 goodyears.

It runs decent but like everyone else out there im looking for more.

ideas: Cam, 2800 stall, 4:10 gears, ditch the bullydog and get a NPtune, ls6 intake.

Im really new to the game ive only had this truck for a year so please share your knowledge with me! Thanks.

Looks like a good plan.

Appropriate cam and forget the LS6 intake and you'll be set

do the cam and stall and NP tune keep your truck intake for the torque, read up on the LS6 intake swap before you think about doing it.

I would toss that paper weight you call a TB spacer also. Unless its the type that adds 150hp at the flip of a switch and push of a button. :lol:

Thanks yall ill keep it updated

What cam would you recommend?

212/218 on a 112 lsa, trailblazer converter, and longtubes. I may have some parts for sale soon if I am able to get the truck I'm looking at. Where in Texas are you?

id run a vette servo too pretty easy and straight forward to do good bang for the buck seeing as its only 20 bucks shipped from oregon performance transmission. i believe they are good untill you run above a 3k stall after that its recommended you go to a billet servo. do the electric fan swap too. just my two cents
