Sister Block 2 with 4.155-inches of stroke, an 830-cfm Holley, and an aggressive Comp Cams roller mechanical cam delivered 131 more horsepower and 105 more lb-ft of torque. Like Block 1, Jim and Jeff took what they knew worked and applied it to the 482 to get the 641 hp and 608 lb-ft of torque. There are always ways to make more power--more cam, a larger carb, advanced timing, richer jetting, and bigger heads--but you also want durability from your FE or all the power in the world won't make any difference. It's always a compromise between power and durability--an engine that will finish the race. Stroking the large-bore 427 to 482 ci gives this mill deep lungs and more torque. This is what 4.155 inches of stroke from a Crower billet crank will do for the 427 block. Here's what's inside.
