Ryan sets the Scat crank with a 3-inch stroke-that's right, 302 ci. We could've stroked this Boss 302, but we wanted to retain its high-revving qualities. Ryan set the bearings and splashed on engine-assembly lube. Once the crank is set, Eric snugs the main caps. He'll torque them in thirds: No. 3 cap, No. 1 cap, No. 5 cap, then Nos. 2 and 4 caps. With each torquing, he'll check the crank for freedom of movement. He should be able to turn it with his fingers right up to final torque. If it becomes too tight, clearances are in error.
