Cold engine knock could be from line bore issues which some 302's were reported to have. It may not be a problem on a stocker but could be something to worry about with horsepower increases.
If you are willing to take a risk, keep the so bottom, bolt a set of twisted wedges, rockers, push rods, ho cam, ho computer, ho upper, 19# injectors, exhaust. Dollar for dollar these mods are hard to beat :evilgrin: :evilgrin:
