Swap In A Box Kit-LS Engine Into 67-72 GM Trk

The TRANS-DAPT Swap In A Box Kit for LS engine conversion into 1967–72 GM trucks is a comprehensive engine swap solution that enables classic truck owners to upgrade from original powerplants to modern LS-series performance. This all-in-one LS engine swap kit includes everything required for the conversion: crossmember support, gasket sets, complete hardware package, headers, engine and transmission mounts, oil pan, and pickup tube. Compatible with both automatic and manual transmissions, this kit eliminates the guesswork of sourcing individual components and ensures proper fitment to GM fullsize trucks and SUVs from the classic era.

The kit addresses the core mechanical challenges of LS integration into older GM platforms: engine bay geometry, fuel and oil circulation, exhaust routing, and load transfer. The included crossmember is engineered to distribute the weight of the LS engine properly while maintaining chassis rigidity. Gaskets and seals are matched to both the engine block and pan configuration, critical for leak-free operation. Headers are tuned for the 1967–72 truck chassis constraints, optimizing exhaust scavenging without excessive heat transmission to cabin or underbody. The pickup tube and oil pan assembly integrate with the LS lubrication system, ensuring adequate oil supply under all driving conditions. Transmission mount provisions accommodate both TH350/TH400 automatics and Muncie/Saginaw manual boxes, allowing buyers to retain original transmissions or upgrade to modern alternatives.

This kit serves hobbyists and professional builders undertaking classic truck restoration with modern performance goals. The LS engine platform delivers reliability, parts availability, and power density unmatched by original 283, 350, or 454 big-block engines, while the classic truck chassis provides timeless styling and driving position. Buyers who complete this conversion gain a usable, dependable daily driver or show vehicle without the long lead times and cost of custom-fab work. At 59.53 lbs, the kit's core components ship efficiently without compromising structural integrity or fitment precision.
