If you’re on a tight enough budget that your considering replacing the engine in a vehicle with that high of miles then you’re not spending your money wisely by dropping $6-7k into a vehicle that’s worth $6-7k, if that.
If it needs an engine, low mile 5.3s are plentiful and way less money.
If you’re dead set on a new engine, that same $ along with the salvage value of your rig (now while it still runs) would be better spent on something with way less miles.
Unless you’ve already literally replaced or rebuilt most every major component and are more certain than average of the remaining lifespan of the vehicle and what you’ll need to do to keep it on the road.
