I just built a new motor for a c10 with an old school sbc that I am finishing up, I called Lunati and had a 20 minute conversation about hydraulic rollers and certain aspects of LS engines. I ended up with a hydraulic roller with .560" of lift that comes in at 1900 and red lines at 6,200. I have not driven it down the road yet (I still have to bleed the brakes) but this thing rips like crazy. If I was to build another motor for a buggy this style cam would be in it. Pure grunt with very good vacuum and a rumble for an idle. I put the same convertor that I had in my last Rockwell rig, a b&m holeshot 2,400, I love these convertors they do very well on the trails.
