6.0 swap.
The fuel injector connections are different and depending on what year LQ motor you get the MAF/IAT could be differnet. You can fix the injector issue by just swapping over your LS intake with injectors. 01 and later trucks have an intergrated MAF/IAT sensor with one five wire conection. If you retain the stock F-bod intake ducting with MAF and IAT you will be fine. I assume you are talking about swapping into your 98 F-bod? If so swap the 3 wire temp sensor over to the LQ motor as well.
