+1 on the fuel injection. theres a slight learning curve at first but once you get just the smallest concept of it, you will love all the perks of it. plus the LS was designed to run that way.

anyway, from all the searching i did, it seems most of the time you stick with either one or the other for accessories. there might be 1 or 2 things that are interchangable but for the most part they are not. that includes the intake and TB as a car intake/TB will hit the upper hose on the truck water pump.... so whatever you can get cheaper id say.
