Swap In A Box Kit-LS Engine Into 67-69 F-Body

The TRANS-DAPT Swap In A Box Kit for LS Engine into 67-69 F-Body vehicles is a complete engine conversion solution engineered to simplify one of the most demanding modern modification projects—retrofitting a GM LS-series engine into classic second-generation Pontiac F-Body platforms. This kit consolidates all the critical components needed to install an LS powerplant into 1967–1969 Pontiac Firebirds and Tempests, eliminating the guesswork and fabrication headaches that typically accompany such conversions.

The kit includes purpose-designed engine mounts, a crossmember engineered for LS fitment, custom headers optimized for mid-body installation, an LS-compatible oil pan, pickup tube, gasket set, and necessary hardware—all validated for automatic transmission vehicles. This comprehensive approach addresses the three primary installation challenges: structural support (crossmember and mounts), manifold routing (headers), and lubrication compatibility (oil system components). The inclusion of a factory gasket set ensures seal integrity from the start, while the pre-engineered header design minimizes clearance conflicts common in tight classic engine bays.

This conversion kit targets serious enthusiasts and restoration shops performing LS swaps into first and second-generation F-Body cars. The LS platform delivers substantial power increases over original 400 or 455 cubic-inch engines while providing modern fuel injection, reliability, and parts availability. Builders prioritize this kit when planning restomod projects that demand structural integrity, proper drivetrain integration, and bolt-on compatibility—eliminating months of custom fabrication work. The 83.63-pound kit ships complete and ready for installation planning.
