World Products has introduced a new lightweight cast iron small block for racing and performance applications. Weighing in at a nominal 178 lbs., the Motown Pro Light-Weight SBC is cast from a special 40,000 psi iron alloy for increased strength—while weighing significantly less than typical aftermarket blocks. The new block is available with either a standard SBC cam journal or lifters—or with a BBC cam journal and .904 in. lifter bores to provide enhanced valve train stability and performance.
