GM Performance Parts LSX 454 - Is Everything Bigger In Texas?
|
A set of custom-made Diamond Racing Products forged pistons are used in combination with Total Seal piston rings to ensure the 11:5.1-compression crate engine will be able to reliably live on the street or at the track. Jason continues, "The pistons use 2618 alloy with 3.8cc valve reliefs and are considered severe-duty and power-adder capable. With the ring pack specified for the pistons, you can reliably run a 150 shot of nitrous. For max-effort naturally aspirated racing or boosted applications, custom Diamond or Wiseco pistons are available for the 454 LSX for an additional $325." The connecting rod is an Eagle H-beam forged 4340 unit that uses a 0.927-inch wristpin supplied by Diamond Racing/Trend Performance. Double Spiralox retainers are employed with the free-floating wristpin. View Related Article
