I had a Trailblazer, saw one of the engines out on a stand at the dealer. They are TALL, it's a DOHC. Front axle goes through the oil pan, diff is bolted to the side. That was done to save heighth. Thing must be close to the heighth of a smallblock with a tunnel ram. The I5 is essentially the same engine minus one cylinder.
