A NOS 302 camshaft is not a "performance grind," unless perchance it comes from Howard, Herbert, Iskenderian, McGurk, or some other manufacturer of speed equipment. i had a NOS 302 cam reground by Donnie Johansen to the Howard specs, and the change in its physical appearance was quite remarkable. You can "see the difference."
A stock 302 made peak power at 3,400 rpm, and peak torque at 1,600 rpm. If you plan to haul bricks or pull stumps with your truck, you will do well to find a stock 302. There is, as we used to say, "no substitute for cubic inches" where that kind of power is needed. Your rebuilt 248 could benefit from more carburetion, compression, and improved "breathing"--bearing in mind that gasoline will only become more expensive, not less. The most useful improvements you can make may be a higher (lower numerical) rear end ratio and larger tires that will allow quieter and more economical operation at a higher "cruising speed."
God's Peace to you.
