L&M Engines LM2400 – 5.0L Coyote Sleeved & Reinforced Short Block

Along with the weak cylinder liners in the stock 5.0L coyote engine block, the water jackets are another significant weak point in its design. We have developed a laser welding process where we weld in struts at the top of the water jackets which eliminates the potential for that particular failure. Our reinforcement is superior to anything currently on the market because we do not rely on a mechanical connection to transfer stress.

For high power applications we recommend having our head bolt modification to eliminate cracking in the valley by the knock sensors.
