Im not too much of a cam expert. but you do know you cannot use replacement 318 pistons, you'll need to find some stroker 318 pistons to work with that crank. low 13s for a 3.55 geared 3,800lbs is asking a lot out of a 318. Anything can be done if you put enough money into it, i'd look into edelbrock heads, a GOOD torque converter, and whatever cam comes recommended from the crowd. just my 2cents
