Granted, doing something different is always cool.
However, doing some for cheap is cool too. lol.
Part of me would like to do something besides a Chevy but it seems to be the cheapest way to go. If money was no object I'd build a real nice stroker, but a 5.3 can be had complete for under a grand. It's lighter than the 4.0, and decent power. My biggest concern in the low rpm torque. I love my 4.0 for that. I just don't think the 5.3 will lug like the 4.0 does.
