Big duration cams need compression to work right. At lower rpm's they don't build as much cyl pressure. I have gone through 4 cams on my 396 in the last 10 years. Started small, then went big, then backed it down a bit, now I have the smallest duration cam the motor has seen yet. It is more fun to drive, but it idles really smooth. Quarter mile times never changed as much as I thought they would, but the "seat of the pants" impressions sure changed. Everything in a motor has to work as part of a combination, so blanket recommendations for what cam you might be happiest with gets tough. I like tons of torque for passing without downshifting, it's more fun than peaky high rpm HP.
