540 Chevy Big Block Engine Build Checking Piston To Valve Clearance
|
Once the heads were bolted into place, Shoemaker set up the pushrods and rocker arms on one cylinder to check piston-to-valve clearance. Shoemaker does this by bringing the piston up to TDC, zeroing the dial gauge, then tightening the rocker bolt and compressing the lifter until the valve touches the piston. We had more than 0.130 inch clearance on the intake side and more than 0.155 inch on the exhaust. View Related Article
