Dan,
Stock cams not only have a lot more duration and overlap than you'd want, but also a lot more aggressive lobe profile than you'd want in a street flat tappet cam.

Attention to detail is what makes Stock engines run.

Honestly, using a set of aftermarket heads with modern ports and combustion chambers will get you years ahead of what we're working with to make these older heaps go fast. The same thing with pistons, more efficient dish/dome profiles, better skirts, and better ring packages will be a lot cheaper and work better than what we run.

What you need to take away from the typical Stock program is the attention to detail and the blueprinting that allows us to make the most of the limited stuff we have. The use of torque plates, the perfect hone finish, the blueprinted locations of the deck, the main bearing bores, the lifter bores, the cylinder bores, and the exacting tolerances and clearances.
