Jack Clifford, when he was alive, had as much, likely more, experience with camshafts for the 235 Chevy then anyone. I have run a few of them over the years and they were very good cams. I still have one I have never run, Giant size cam, way too big to ever run, from when I was way younger and bigger was always better, lol, so that one will get reground at some point. But jack’s descriptions of his cam grinds I always found to be accurate so here is a page out of one of his old catalogs that might help with assessing what you have.
That being said, I have had very good luck with jerry Cantrell at Schneider cams in San Diego. They are pretty good and if you want a little rumble out of the 235 at idle, give them a play. They will grind you a cam that makes sense for your build, which is particularly important when running an automatic.
