Just FYI, a solid roller of that size will need some pretty fat springs, which are not easy to fit in a small block. It can be done, but most springs for a cam that size are at least 1.55" in diameter and will require a high quality rocker to survive under the high spring pressures (probably about 220lbs on the seat and 600lbs open I'm guessing). Just something to consider when pricing stuff out.
