GM Gen 5 LT1 & LT4 Budget Re-Sleeved aluminum block.  Sleeved right here at Mast Motorsports in our state of the art Haas VF4 CNC machine.  

We utilize the 5.3 GM Gen V LT Block as the base for the re-sleeving process.  Utilizing a specially designed sleeve that does not cut into the smaller water jacket opening on the deck.  This allows for converting a 5.3 LT block into a more desirable 6.2 configuration.  The added strength of the aftermarket sleeve gives you enhanced durability over the stock configuration, and allows for slightly larger bore sizes that a stock OE LT 6.2

Sleeves are pressed in with loctite and aircraft sealer to maximize the mechanical bond of the sleeves.

Our manufacturing team vibratory stress relieves all blocks to ensure all negative residual stress is removed from the sleeving process.  

All Blocks come STANDARD with Block Machining & "Blue Printing"- Line Hone, Decking, Rough Bore, Vibratory Stress Relief.

Specs:

  • Decked to 9.230"
