Mauler 440 Engine Spring Clearance
|
We wanted to make sure we had plenty of spring on hand to dispel the chance of valvetrain instability, and the roller cam allowed us to raise the bar significantly. We used Comp's No. 999 spring, a premium H-11 steel dual spring measuring 1.550 inches. This spring delivers stout force, with 196 pounds of pressure on the seat and 608 pounds at max lift when installed at 1.900 inches. View Related Article
