      Texas speed LS rocker arms

      Posted by Mike koch on May 26th 2024

      Good looking rocker. Used on LSA. They state need a pushrod .175 shorter than stock. I went .150 shorter to get just over .100 travel into LS7 lifters which is center of plunger travel, .175 would have been perfect with regular LS3 lifters . Motor nice and quiet with .610 lift , 228/237 dur. Cam and .660 dual springs. Seems like a quality rocker!
