I want to know which cam company would you recommend I want to get a custom solid roller cam made for my 273 I don't think the ones out there were made with my application in mind. Right now in my dyno program I use Comp Cams XR269R http://www.compcams.com/Company/CC/camspecs/Details.aspx?csid=686&sb=0 and it gives 426HP @ 6600 rpm and a pretty flat powerband from 2000-7500 rpms.
