While big block engines, regardless of the make, are the de facto choice for serious drag racers looking to make horsepower and drop those elapsed times, there’s nothing quite like getting the job done with a small block, and high performance aftermarket manufacturers like GRP have all the parts one needs to make that much-needed horsepower the old-fashioned way.
GRP, makers of some of the industry’s leading connecting rods for racing applications, offers a number of rods designed for small block engines in their “SB” series of rods. These include the aluminum SB 1000 lightweight rod commonly used in NHRA Competition Eliminator and Super Stock with 3/8-inch ARP bolts, .800-.927-inch wrist pins, and 2.125-2.250-inch housing bores, the SB 1100 middleweight rod for nitrous engines and high-horsepower bracket cars, and the heavyweight SB 1200 for supercharged small blocks featuring 7/16-inch ARP bolts and .925 or .990-inch wrist pins.
One of the latest small block rods offered by GRP is the SB 1400, which reduces rotating weight thanks a smaller profile and is designed around smaller 1.888-inch crank journals. These have 3/8-inch ARP bolts and a 2.000-inch housing bore. The SB 1500 series rod, likewise, is a lightweight rod designed for 2.000-inch crank journals and is similar to the aforementioned SB 1100 but with narrower bolt spacings.
In addition to the specific rods highlighted in their catalog, GRP offers complete custom services and as such, can produce rods for small block engines (or any engine for that matter) per the customers’ needs. If they don’t offer it, they can certainly make it, so for all of your high performance aluminum connecting rod needs, be it for a small block, big block, or other engine combination, visit GRP Connecting Rods.
