Emailed Comp cams for a camshaft recommendation.
I've been hearing complaints about flat tappet cams going flat due to inferior materials being used. Is this a non issue in a roller motor like the L31, or are manufacturers cranking out crap on those as well?
Your memory is correct. However I found out later valve float was a contributing factor. Insufficient spring pressure.Just make sure you specify a billet core. Both the cams in my trucks have billet cores. @L31MaxExpress ate a cast roller comp cam of I'm not mistaken.
