LL8 I6 possibilities...

I'm looking at bellhousing patterns and it looks like the I6 from a 2006 Chevy TB has the same pattern as the Chevy V8 platform. Using the Quicktime RM-6033 this might be an easy swap, and be a mild in-between for the 4 cyl and the V8s instead of the 3800 series V6s. The major point of problems with engine swaps looks to be steering shaft clearance, this engine configuration may eliminate that. I have seen where people have fit the VW VR6 engines in the bay and had minimal issue with the steering shafts and exhaust manifolds/headers.

My main worry is that the I6 will be too long for our engine bay, and the intake from the trailblazer will for sure be too tall. Has anyone else seen a swap like this or even looked into it. Just wondering what other peoples thoughts are.
