I got a cam from Patricks for my 261 that was "OK" but the lifters were apparently soft and were worn out at very low mileage. I replaced it with a cam from Delta Cam in Tacoma, WA and have been VERY happy with it. The engine has twin Holley-weber carbs, Fenton headers and electronic ignition. The cam they sent me was just right for my application but they can provide pretty much anything you need. My 2 cents worth.
