well i have a 1996 silverado ext cab 2wd 5.7 vortec and i just got it and the tranny is new i have paperwork and all. but the engine has over 212000 miles on it and i just purchased some pacesetter long tube headers and a trick flow cold air intake. but i really want to rebuild before i put all the extras on this high millage engine. so any suggestions would be nice. my budget is about $3000 labor and all, and my goal is to get about 300hp to the wheels and i will have a certified mechanic do all the work and this is my daily driver. and should i think about gears??? thanks guys!
