Description
TSP's fasteners are composed of 35 chromoly steel for a minimum tensile strength of 190,000 PSI. Threads are rolled after heat treatment, and then tested for tensile and yield strength. All hardware is then given a black oxide finish and oil coating to protect from rust and corrosion. The included hardware is matched to the intended component style to support a clean, secure installation.

Engine Fitment
COMPATIBLE WITH
Ford Small Block Windsor V8
• 5.8 L / 351 in³
NOTES
• Designed for Ford 351W Windsor small block V8 engines with 2-bolt main caps.
• Verify block configuration (2-bolt vs. 4-bolt main) before ordering, as main cap bolt patterns differ between the two designs.
• Not compatible with Ford 289/302 Windsor blocks unless main cap dimensions specifically match — 351W uses a different bottom-end architecture than the smaller-deck Windsor engines.
• Not compatible with 351C Cleveland, 351M, 400M, FE, or 385-series Big Block Ford engines.
COMMON VEHICLE APPLICATIONS
• Ford Mustang small block Windsor engine builds
• Ford 5.0L and 351W street and performance applications
• Classic Ford small block V8 engine installations
