This may be a stupid question, but wouldn’t it be easier, cheaper, faster, more safer, etc to just trade/sell the 4.3 and get a 6.2?? Trucks these days aren’t like the 80s where you just drop in another bigger engine and everything works. There’s too much electronics and wiring that would have to be altered. Seems like a crazy task, but hey, more power to you. Sent from my iPhone using Tapatalk
