Racekrafters 467Ci Stroker Butler Performance Billet Aluminum
|
[14] The Butler Performance billet-aluminum valley pan provides the clearance needed to run our hydraulic roller lifters. We chose the PCV-style, which uses a double-baffle design to thwart oil consumption through the PCV. When installing it, he warns not to over-tighten the hardware—as he has seen people do in the past—because it can distort the pan. He uses a pair of jamb nuts on each stud just below the height of the front and back sealing flanges of the block to act as a positive stop. View Related Article
