340 cam in a 318

thats the hemi grind isn't it? i had that cam in a 69-70 stock 318 many years ago,, i forget if i had the J heads on that motor or not. had 3.23 gears in it, small eddy carb and headers.. car ran damn well... idled and drove stockish.
Was it the .474 or .484/284 that they called the hemi grind.... my mind draws a blank
