I was wondering if anyone has swapped their 6.0L with a 5.3L and how easy it is?

 

I just did mine 2 weeks ago ...Very Easy as long as you use the same intake system ...via return style or retunrnless...The hardest part is getting thet tranny unstuck from the back

here is a good link

 

why would you swap a 6.0 for a 5.3? or did you just word that wrong?

I did mine this summer..and i agree, the ****** hardest part was gettin the trans and motor apart..we had to pull it all together and use 2 big *** prybars...pain in the ***

 

HA HA I did it that turd by myself using a come-along on one side and a huge pry bar on the other....pain the ...ending up bending the 1" bar with the come-along ...but yea alot of fun

 

Maybe he wants less power

 

or he saw that bill is runnin a 5.3, thinks that he is N/A. pushin 626 hp

 

That number is N/A dude...

Bill can't afford a supercharger, especially after all the new bodywork and paint he got done

 

my guess is that he just can't keep his foot out of it & this was his last-ditch effort to avoid trouble

 

It'd be a lot easier and cost effective to tune it with lower timing and RPM/speed limits.

 

oh yeah... to the OP:

the short blocks swap right out
