7 A hardened one-piece pushrod is your best bet when you upgrade to an adjustable valvetrain/rocker arms. The Magnum and Hi-Tech pushrods from Comp Cams feature 0.080-inch seamless wall chrome-moly tubing with formed ends, heat treated and finished in a black-oxide coating with laser-etched part number and length on the body. You have less deflection with one-piece pushrods due to their thicker walls and better materials. One-piece pushrods are more exacting with higher production tolerances. You can make more power with a better pushrod, as at higher rpm, you get less lift with a deflecting pushrod. The Comp Cams staff we spoke with suggested putting the best pushrod you can in your build. They have seen 10-15 rwhp with the use of a stronger pushrod. View Related Article
