The TSP-400SB-RESL-LT from Texas Speed & Performance is a robust choice for those looking to enhance their engine build. This short block features a new, resleeved Gen 5 aluminum block equipped with Darton dry sleeves. These sleeves are not only thicker than the standard GM sleeves but also offer superior tensile strength, making them a reliable option for performance enthusiasts.

One user mentioned, "I installed this short block in my Camaro, and the power increase was noticeable right away. The machining is top-notch!" Another customer noted, "The Darton sleeves give me confidence that this block can handle the power I'm throwing at it." These testimonials reflect the reliability and performance that Texas Speed & Performance is known for.
