I'd have to agree with Jetmech with a ZR2 Blazer; those 4.3 liters are pretty dependable as well. I've had two; well one awesomely modified 4runner with a chevy 4.3 that took me through some awesome trails in the mountains and even survived a slight rollover lol "rock crawlin" however currently using a ZR2 Blazer for my winter vehicle. Its nice and sporty, has a higher stance than what the regular blazers came with and best of all its something that suffices in stock form. I wanted something that I wouldn't be tempted to to make it into another money pit by adding all sorts of mods etc in turn taking away $ from future Cobra mods lol.
