ALL  ROLLER ROCKER ARM SET - Part Number 12370838
Roller Rocker Arm Set 1.5:1 Ratio 3/8 Inch Studs Aluminum. These roller rocker arms are similar to the rockers used in the 1996 Corvette LT4 engine, except the trunnions have been machined for early-model 3/8-inch rocker studs. These arms offer about 2 lb. ft. in rotation torque for a quieter idle. The arms are self-aligning with improved stiffness and accommodate up to 0.575-inch valve lift. Choose from 1.5:1 and 1.6:1 ratios. Note: When using a high lift camshaft, check valve spring coil blind, retainer-to-seal clearance, and piston-to-valve clearance. Check for adequate pushrod clearance when using on cast iron heads. It may be necessary to remove valve cover drippers for proper rocker arm clearance.
