alright i got a 4.3L stock engine all the way in my 02 silverado. i cant switch out the engine cause my dad says no, but is there anything else i could do to get more power out of it?

 

basic bolt-ons bro...intake, udp, gears, exhaust

 

+1 and maybe add a tune from one of the sponsers to the right ------>

 

here is everything i have done to my 4.3 right now.... JBA shorties, custom Y-pipe, underdrive pulley kit from March Performance, Taylor 8mm wires, NGK plugs, Accel ignition coil, MAC coldair intake kit, Jet 2nd and 4th gear servos, TCI deep tranny pan with cooling fins and tranny cooler and a tune from Charlie Wheatley

 

full boltons, tune, gears, stall, shift kit, and 100shot

 

alright thx. im gonna do some of this. prolly intake, cervos, and exaughst for now. but im gonna stay away from the 100 shot...id get in trubble
