Engine Swap 2007 GMC Canyon 2wd 5 speed

[Backwoods]

I have seen some Canyon's with a 5.3 in them from the factory. I've bought one with a 2.9 in it and the motor is knocking so I have to pull it. I am thinking about putting a 5.3 or a 6.2 in it. Is it going to be alot of changing or will it set right in? Also, will that 5 speed bolt up or am I gonna have to get another transmission? I thought about putting a old school 350 in it too? Which would be easier? or just put the 4 cylinder back in it and sell it to save time and money?

The five speed could bolt up but I am unsure. To swap in the 5.3 you will need a new engine harness, tune, probably some motor mounts and possibly an ecm but that I am unsure of. I would put the 4 banger back in and sell it if you are not too attached to it
