“I installed the TSP-454LSxLB in my 2010 Camaro SS, and the difference is night and day. The power delivery is smooth, and the torque is incredible. I paired it with the PRC 260cc heads and couldn't be happier with the results!” - Camaro SS Owner

Important Notes

• Designed for competition use only; not legal for road use.
• Expect a lead time of 6-8 weeks for LSx/Dart based builds due to block availability.

Break-In Oil Included

Every TSP engine comes with 12 quarts of break-in oil at no extra cost. This is crucial for ensuring proper ring sealing during the initial startup and break-in period. We recommend using Driven Racing HR2 conventional oil after the break-in is complete for optimal performance.
