i have a tahoe 2007 and i wanna replace an engine with 6.0 L with my engine which is 5.3 ... does anyone know anything about this ? i mean if it's ok to replace it directly or i need to do some operations first !!!!

 

Welcome to the forum. Maybe ZX can answer this. I suspect that it will be expensive if even possible. If you're looking for more power, there's probably going to be cheaper ways to go.
