I have a 2014 GMC Sierra 1500 4.3 tired of how slow it is wanna swap in either 5.3 or 6.2 is it worth it or no ? I've done motor swaps before on old truck will this be harder and suggestions ?

 

In my opinion just trade the truck in for a 5.3 or 6.2.

 

That would be best option.... Depending on what you owe on it etc.... However yes it would be worth it....

 

If you owe a lot.... theres always forced induction.

I bet that little 4.3L would love 8-12 lbs from a centrifical S/C

 

Just like everyother chevy. Find a same year donor pull it all out drop it all in. But as stated if you are not upside down or loosing money trade it in walk away being a v6 it's probably a stripper so you can gain a nicer truck all the way around.
