Hello! I have a 1998 Silverado K1500, extended cab and short bed. It has a 5.0 Vortec in it, with a rebuilt transmission and pozi lockers. Sadly, my father decided to take it out and play mad max in a field, (It was raising hell for street treads.) And the bottom end started knocking and went out. I have a 1999 LS Silverado with a 4.8L LS Vortec I bought for 300 bucks with a destroyed shock and frame. I know my 1998 uses a white and black PCM unit type..... thing. I do not know the style of the LS 4.8, but I know it's different. I am going to pull the 4.8 out and replace the 5.0 with it. What electronic hell awaits me? Somebody on Gmtruckclub told me I would be doing what's called a ... 0411 swap? Any advice would be appreciated greatly.
