Ok here goes. I am new with the S10 scene. I just bought a 85 blazer 4x4 auto. It has a 2.8, the motor knocks but every thing else works perfect. I want to drop a 283 in place of the 2.8, where will I find info on how to go about this? Also has anyone tryed to drop a 4x4 & still keep it functional? Any info on any of this will be really helpful. Thanks J.J.
