well just looking performance, the 96 and up v6 (VIN X in the pickup rated at 180hp and W in the blazer rated at 190hp) has more porformance potential and there is a larger aftermarket part backing. one of my friends has an 03 v6/5spd s10 and stock it ran a low 16 and after a bunch of boltons is maybe in the 14sec range. the 95 cpi engine doesn't have as many aftermarket parts available for it but it has a better hp and torque curve do to the intake manifold. its rated at 195hp. read the stickys at the top of this section and threads called "real performance from a vortec v6" and "v8 performance from a v6" for some ideas on what is posible with these trucks. if you have any other specific questions let us know
