Have you looked into the inline 6 that GM is using in the current Trailblazer? .... They are fuel injected, which adds some complication to the issue, but I believe well worth it in the end.

Devin: I would REALLY like this engine, if it did not require a complete computer, wiring harness, and army of sensors. That extra complexity is way outisde the SLURP mission statement. IF someone supported this engine in a carbureted versus injected mode, I would probably look at it seriously, even though it would require some work (cam change at least) to get to the minimum 300 crank horsepower on my wants list.
