i went with the 4.3/th350/np205 combo. i chose the 4.3 b/c of availabilty and i was planning on running propane and i want a simple reliable setup, something i can actually work on if need be. The 3.4 would still have tons of wiring to fool with. I'm not scared of wiring ( i work for an electronics company), i just want to simplify and eleminate all that. my truck had the 3.0 and i was always woried about have electronic issues, but the poor thing didn't last long enough for any issues to come about.
