i had one in a truck with sbc, 465/205, 38" cut boggers for about a year and a half. took it out and now it's in my 85 with a 383 and q78(36" super swampers). i noticed some wear on it when i switched it from one to the other, although it's had a hard life and i wouldn't hesitate to buy another one which i will to put in my blazer with 1 tons.
