Greetings from the Las Vegas Convention Center – home of the 2017 Specialty Equipment Market Association (SEMA) show. We are excited to promote our new SB4 7.0 (Small Block Four Valve) automotive aftermarket crate engine. The SB4 earned two Global Media Awards upon its 2016 SEMA debut.
Designed, developed and manufactured in-house, the naturally aspirated, 7.0 Liter DOHC V8 Small Block Four Valve (SB4) engine features Mercury Racing’s exclusive aluminum four-valve cylinder heads and dual overhead camshaft valve train integrated with an 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 8,000 rpm on pump fuel.
The SB4 is intended for use in pre-1968 muscle cars, street rods and an array of road track and off-road competition vehicles.

This isn’t Mercury Racing’s first road trip. The late Carl Kiekhaefer, founder of Mercury Marine, revolutionized NASCAR from 1955-57. Kiekhaefer dominated the sport by winning 80 percent of the races he entered and capturing three national championships.
In 1990, General Motors approached Mercury Marine to produce the all-aluminum, 5.7- liter LT-5 engine for the Chevrolet ZR-1 Corvette. GM came to Mercury for its expertise in the design and manufacturing of aluminum engines for the marine environment. The ZR-1 was a world-class sports car in its day. The DOHC, 32-valve V8 produced 405 horsepower at 5,800 rpm.
