Texas Speed & Performance TSP-376SB-RESL-LT1 Short Block
The TSP-376SB-RESL-LT1 by Texas Speed & Performance is engineered for high-performance applications, utilizing a new resleeved Gen 5 aluminum block equipped with Darton dry sleeves. These sleeves offer superior tensile strength compared to standard GM sleeves and are significantly thicker, enhancing durability and performance under stress.
Specifications
- Material: Resleeved Gen 5 aluminum block with Darton dry sleeves
- Bore Size: Recommended maximum of 4.125 inches for power-adder applications
- Piston Options: Choice of Wiseco or Mahle pistons included in standard pricing; larger bore sizes available for an additional cost

Engine Assembly and Break-In
Each engine is fully machined and assembled at Texas Speed & Performance's facility.
