Try calling Schneider cams in San Diego. They have been in business for many years. Jerry Cantrell is the owner and has been for like thirty years maybe more. You will get to talk with him. Tell him your combo, car, weight, transmission, rear gears, and what you are trying to accomplish. He will recommend a grind for you and then grind you a cam. He did my last two cams. One cam I Am currently using in my 261, the other is in my stash of parts for another motor. The one I have in my 261 is hands down the best sounding and running cam I have used, and I have used quite a few over the years, Isky, Herbert, Howard's, one Clifford. The Schneider runs and sounds the best. You will pay a little bit more than an Isky off the shelf cam, but you get a custom ground cam that will run really well.
