5.3 or 6.0 ls dilema

[theuglyduckling]

i've got a 76 shortbed stepside RWD i use as a daily driver. Its a bit rusty and has a decent running 350 with a TH350 backing it. Factory gearing out back as well. I've been throwing around the idea of doing an ls swap. I would really prefer the comfort, convenience, and reliability as well as efficiency of doing an ls swap. Plus the cool factor is a nice touch. I am really just looking to make a nice streetable fun reliable truck that has some power for when i want to play a little and is there when i need it, but is dialed back enough for the perfect daily driver to cruise to and from work. I dont have time to do it myself or the resources at hand so i am going to be out sourcing this swap. I was quoted an out the door price of 4500 for the 5.3 and 5000$ for the 6.0. I will be doing some periodic towing of a boat and such with it as well(yes it will be lowered but not slammed to the ground). I will back either with a 4l60e most likely( i would go 6 speed manual but that makes for an uncomfortable ride for the lady when out on date night). Im looking to get recomendations from those who are either also planning or have done both swaps. (i like the idea of removing all decals and having just a 6.0 decal on the side). Ideas, opinions, facts..... send em my way
