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
