I always thought accel made the cams for Lingenfelter. They advertise the 74211 on their website as .530 / .560 with 1.6 rockers. My cam from them came today and its a comp cams grind cam. Same 211 / 219 duration, and the cam is rated at .501 / .526 lift. That makes it .534/.561 with 1.6 rr right? I doubt the extra .004 / .001 will make a difference, but has anyone else noticed LPE cams no longer come from accel? Anything else on the cam card I need to check to make sure it is the same? The lsa matches the website at 112...
At one time Lingenfelter sourced their cams from Accel which had them manufactured by Comp Cams. When Mr Gasket (the parent company of Accel) purchased Erson Cams, they moved the manufacturing of the cams to their own subsidiary. Lingenfelter continued purchasing cams from Comp Cams. You might notice a slight difference in the grinds due to the different manufacturers.
