well, no matter what you do to that blazer, a powerstroke (aka a REAL truck) will tow you around all day like its nothing hahaha i'm just kidding, gotta stir up the chevy guys. anyways, don't forget to consider your driveline, the truck's not really built for a ton of power (reliably) without a good going over first. v8 swaps are no fun unless you get to beat on 'em. and breaking things gets old quick if its a daily driver.
