I don`t see a problem with the cam, it`s the heads I see as a problem. They have a necked down intake port about 2" down or so and don`t flow for nothing. They should be 64cc`s as well. Whats the head casting number? You`ll make some good torque but you would see 400-425hp owith those heads. Bigger vlves and port work isn`t going to chage the design of the heads and won`t help much. don`t get me wrong, I`m not trying to knock your combo. aside from the head choice I think it will be a great street motor for a heavy truck.
