My family purchased a 1996 Blazer 4x4 new, I still have this vehicle with 170,000+ miles and still all original powertrain, the most major things replaced would be the ball joints, tires, CPI, heater core and AC compressors. I also own a family purchased newer (at 10k miles) 99' Silverado 4.3 Vortec, I just did a video on the intake gasket replacement. I am just waiting for permission to post this on the forum so someone can search for it in the future when the time comes. I've beat the hell out of this truck, replaced the reaction sunshell, heater core, spider gears in the rear, and them blasted intake gaskets now; 175,000+ miles on this truck and the amazing thing is all stock balljoints and hubs still!!
