For the 1500 miles i've driven mine, its just as reliable as stock. I drive it almost everyday and haven't had a single problem.

It you don't go to crazy it is just as reliable as stock. I get 16.5 hwy mpg, and drive it every day. Only problem I have had is tranny problems, but that is now fixed with an FLT 4l80e.

I have no problems ... Mine's not wild, but it's not real tame either. The biggest problem I have is idle tuning, but that's got a lot to blame on exhaust leak. That would be there no matter what motor was in the truck.

+1 to what these guys have said. Get a reputable builder and have it done right the first time and you shouldn't have anything to worry about.
