I just purchased a 39,000 mile motor to replace the motor I broke a rod bolt in.

It's a good running piece but I would like install a small cam before I install it in the car. I have a RPM intake, headers, 3500 vert and 3.91 gears.

My question is there a cam I can install without having to change the valve springs to bump up the output?
