Throttle body
Interested in a larger throttle body for my 1999 5.2. What types of mods do I need to make to the engine to run a 50mm? Thx-

Should not need any engine mods. Free up the intake and exhaust. Have you fixed the plenum yet? I'd take care of that before modding.

Headers will be a nice compliment to a slightly larger TB.

^^ Yep. More air in needs someplace to go. Without doing actual head work, intake and exhaust is the way to go.

Do not do anything with injectors unless you're wanting flow matched STOCK

Nothing needed for 50-52mm tb but 52 might lose some low end on a mostly stock truck
