The WP143S-M8 is the streetable cut of our WP143 race cam — same .600" lift and the same 143ci-and-up muscle, with the timing moved for a 12:1 build. Power slams in at 3,000 RPM and carries to 7,000 with an aggressive, lopey idle. Plan on upgraded .600"-lift valve springs, adjustable pushrods, performance lifters, and a full professional tune. This is not a bolt-in camshaft.

  • Pro-Street Power: Built for the large-displacement, 143ci-and-up hot street/strip build.

  • Streetable Race Grind: The .600" lift of the WP143, with the timing moved for a 12:1 engine.

  • Early Punch: Power slams in at 3,000 RPM and carries to 7,000.
