Description: The D.S.S. PRO BULLET 331 engineered to offer the perfect balance between race winning power and long term reliability. This engine is a great way to get Windsor power and torque without the expense of a 351 swap or the maintenance problems commonly associated with other stroker combinations. By using a 5.315” rod we are able to use a taller piston for increased stability, better ring seal and longer life. This custom piston also keeps the pin bore below the oil ring for proper oil control. With it’s superior rod/ piston design, excellent 1.63 rod ratio and an ideal ring package for power adders, the D.S.S. BULLET 331 SHORT BLOCK is by far the best performing, longest lasting stroker short block on the market

Race Prepped Production Block * Power Adder Ring Package * NEW! D.S.S. PRO LITE Forged Stroker Pistons * Forged Steel 5.315” Rods with ARP bolts * 3.25” Stroke Cast Steel or Forged crank * D.S.S. Stroker Main Support System *
Excellent 1.63 Rod Ratio

Each D.S.S. PRO BULLET 331 Short Block begins with a with a race prepped block that has been deck squared and equalized, precision bored and honed with torque plates and fitted with the D.S.S. Stroker Main Support System and custom ARP main studs. This combination includes New PRO LITE forged stroker pistons available for most aftermarket heads, premium Sealed Power/ Speed-Pro moly rings and TRW/ Federal Mogul bearings. We use Forged Steel 5.315” connecting rod with ARP bolts and a super strong, Cast Steel 3.25” stroke crank for the ultimate in strength and longevity. We offer optional compression ratios and cam and timing chain options, just tell us what you want and we’ll quote a combination for you. If you are looking for a stroker that makes 30 to 40 horsepower more than most larger stroker combinations and is equally at home on the street or strip, you need the bullet 331 short block.
