Guide to Regrinding Camshafts

I’ve emailed Ken today about a pair of hydraulic rollers. One is a 1990 LA 318 .257/.257 lobe lift and a 1987 318 .278 I /.260 E lobe lift. I’ve inquired if either cam will accept grind number 722, which is 222/[email protected], 277/[email protected], and .309/.320 lobe lift. It comes on a 112 LSA, but Ken says you’re limited by plus or minus one or two degree degrees of what the factory LSA is. Stock LA truck cams are 106 to 111 LSA and the car cams are 114 to 116. I’ll opt for the narrowest LSA possible.
