Lots of people including me have upgraded 2 bbl 318
stock low compression 318 stick with the stock cam and just do carb and manifold
either of those old cam dynamics cams will loose torque
360 cam is not a good fit either
do you have dual exhaust with not too big pipes or large single exhaust- one of the first moves
what toolmanmike says
really easy to overcam a 318 unless you are prepared to change gears, even then
