iam in the process of changeing motors now. i dont have alot of time so i can only do a little at a time. so far all that i see that is differant is the intake, knock sensor, and its a distributerless ignition. the intake is drive by wire. which is a easy fix with my marine intake. under the coil pack on the intake there is a plug that i pulled out. it turned out to be a bottom half of a distributer, so i wont have a problem with installing my old distributer. the knock sensor i will just splice in the plug to matchthe newone. i will post anymore problems that come up,that way if anyone else installs a new motor in their blazer, you will have a heads up on the mods needed to be done for the swap.
