Can You Bore a 5.3 to a 6.0

The short answer is, yes you can. But there’s a lot more to it than just throwing some bigger cylinders at it. First off, let’s look at what exactly you need to do the swap.

You will need: 6.0L LS engine (obviously), 6L80E/6L90E transmission, 2-piece driveshaft, and the biggest part – ECU tuning. The most important thing to realize when doing this conversion is that the 5.3L LS is not simply a smaller version of the 6.0L LS. They are two completely different engines designed for different purposes from the factory.

The 5.3 was designed as an economical engine with good fuel economy while still providing decent power and torque, whereas the 6.0 was designed as a high performance engine from the start.

  • 0L engine block
  • Clean and inspect the block, checking for cracks or other damage
  • Install the 6
  • 0L crank into the block
  • Bore the cylinders to 5/64″ oversize using a torque plate if available
  • Install new rings on the pistons and check ring gaps with a feeler gauge
  • 6)Install the pistons in the cylinders, being careful not to damage the piston rings or cylinder walls

Are 5.3 And 6.0 Blocks the Same?

No, 5.3 and 6.0 blocks are not the same. The main difference between the two is their bore size; the 5.3 block has a bore size of 3.78” while the 6.0 block has a bore size of 4.00”. This increased bore size on the 6.0 block allows for more displacement (6L) and therefore more power potential.

Additionally, the 6.0 block uses siamesed cylinder walls which helps to further increase its strength and durability over the 5.3 block.
