I used a cam that came with the program, your specs wont be too far off. I think the valve sizes might be off a little too, I just used what the program had.

click on the image, then click the white X in the bottom left coner to expand to actual size and you can see the specs I input in the program



I changed to large tube headers and mufflers and it made 388 hp / BUT 485 ft lbs torque at 3000 RPMS!!. Thats why I suggested polishing the exhaust ports
