Guys, I know this has been asked time and time again on here im sure. I see a stricky with some info but most of the posts I found where newer 99+ V6 to 5.3 swaps. Does anyone have any info on the below

project work truck
94 4.3V6 manual fullsize 4x4 w/127k on the clock

I want to swap a newer 4.8 or 5.3 in it(whichever I can find cheaper). I have a 4.8 block I can get cheap. Whats needed for this swap since its a manual truck?

Ill search and read more later tonight and this week but if someone can give me a ballpark idea of how hard this is and whats needed that would be great

Im just looking to spice up a beater truck a tad since my 04 is to clean to farm in anymore
