It includes a forged 4140 crankshaft with a 4.250-inch stroke, strong 6.385-inch 4340 I-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and forged 4032 Mahle flat-top pistons with a -3cc dish, measuring 4.320 inches in bore size.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. It's important to consult your engine builder or refer to detailed assembly instructions for proper installation, including ring gap setting and bearing clearance checks, to ensure optimal performance and longevity for your racing engine.
