I would take the Trail Blazer over a 'Tek or Rendezvous. No doubt I would take a Grand Cherokee over the TB though. I do not like Chrysler at all, but Jeep is the exception for me.
The 5.9 jeep was the fastest SUV in 1998. They got a better tune than the 5.9 Durangos and Rams. I could just barely take my friends 5.9 jeep with my SSEi. He had K&N intake system and high flow exhaust, I think my only mod was intake at the time.
