Racekrafters 467Ci Stroker Valvetrain Durability
|
[8] To improve valvetrain durability, Craig had Cory previously modify and install BBC 7⁄16-inch studs. He placed a 7⁄16-inch washer under each stud to ensure the trunnion of the Pontiac rocker runs on the shank of the stud and not the threads (the weakest part). He then removed 0.300-inch of the thread length, so that the rocker’s set-screw has maximum thread engagement. View Related Article
