on4now4 Posted February 19, 2011 Report Share Posted February 19, 2011 i will attempt to word this so it is not a question. I have a camshaft here and well i don't know what it is. (that is a statement) here are the markings on it, it came in a box when i bought my car and have had it for a year with no idea what it is. http://i129.photobucket.com/albums/p209/on4now4/_IGP5624.jpghttp://i129.photobucket.com/albums/p209/on4now4/_IGP5625.jpghttp://i129.photobucket.com/albums/p209/on4now4/_IGP5626.jpghttp://i129.photobucket.com/albums/p209/on4now4/_IGP5627.jpghttp://i129.photobucket.com/albums/p209/on4now4/_IGP5628.jpghttp://i129.photobucket.com/albums/p209/on4now4/_IGP5630.jpg Link to comment Share on other sites More sharing options...
StarquestRescue Posted February 19, 2011 Report Share Posted February 19, 2011 Looks like a tep hr70. Based on the purple mark and the 70 on the end. Link to comment Share on other sites More sharing options...

StarquestRescue Posted February 19, 2011 Report Share Posted February 19, 2011 (edited) It is supposed to work with either the manual adjusted or hydraulic slipper rocker. Some like them some don't. Mine ran like crap undegreed, but seems fine degreed (advanced 4-5 degreess) with an adjustable cam gear.

StarquestRescue Posted February 19, 2011 Report Share Posted February 19, 2011 Per tepHR 70 Cam You need to set the cam at exact split overlap. That means the intake and exhaust valves are both off the seat the exact same amount at TDC.
