Boosting an aluminum LS? LS1, LS2 and LS3 blocks are open-deck aluminum castings. EPOXY54 block filler is a two-part epoxy (21,000 psi compressive strength) that reinforces the deck to closed-deck strength without machining, with a Partial Fill option that keeps OEM coolant flow. Iron LQ and LSX blocks use the Cast Iron Block Epoxy Kit. Learn more in LS Block Filler: Reinforce Your LS, LQ or LSX Block Without Machining.
