Thinking of doing the LS swap for my 89

[89DEKE]

Thinking of doing a LS swap for my 89. I'm thinking of going 2 different ways with this 1. LS3 crate motor 480hp or 2. finding a low mileage 6.0 and have someone do head/cam/intake swap to get me either to or above the 450 hp that I desire. Guys I'm not mechanically inclined, would love to learn but time doesnt permit so I'm hoping thru some info from you guys I can become educated from y'alls input on what the most cost efficient way to accomplish my build. Info on my truck it has the 5.7 350 with the 5 speed manual from what I understand the tranny from the years are trash so i'll either have to go with a tko5 or swap to 4l80 type auto, I have also read I'll need a/c compressor,alt, ecm,wiring and pulleys. The rearend will also need to be adressed so I'm thinking Detroit truetrac (but open to suggestions) and 3:73 or 4:10's (also open for suggestions). This will be my daily driver no track time maybe a lil romp the the roadways but nothing too crazy. Any help would be greatly appreciated also a shop or individual here in the Dallas/Ft. Worth area that could handle the swap would be helpful too. I would like to start gathering the small parts ecm etc now and do the swap in January. Thanks Deke
