Mercury Racing Reveals SB4 7.0 Automotive Crate Engine


Greetings from Las Vegas! We are here for the 50th Anniversary SEMA Show where we just revealed our latest automotive aftermarket crate engine, the SB4 7.0. The 32-Valve DOHC V-8 was designed, developed and manufactured in-house.

The naturally aspirated, 7.0 Liter engine features Mercury Racing’s exclusive aluminum four valve cylinder heads and dual overhead camshaft valve train integrated with a LS cylinder block packed with Mercury Racing designed and specified hardware.

This proven valve train, which greatly enhances engine durability over a standard two-valve design, enables the engine to produce a staggering 750 horsepower at 8000 RPM on pump fuel!

Benefits of the DOHC four-valve design versus the typical LS pushrod layout include:

  • Improved intake and exhaust flow enables increased engine performance
  • Efficient, high tumble four valve combustion
  • Low mass, high stiffness design reduces stresses and enables smooth high RPM operation and long life
  • Improved drivability due to optimized camshaft timing at comparable horsepower levels
