You can not make any kind of valid choice of camshaft until you decide what you are going to do with the rest of the drivetrain/engine. What compression, carb, intake, exhaust, port work, valve size, converter stall, rear gear, street, strip, multi-purpose.
Just saying you need "X" camshaft is not going to help you much. I've said it before and I'll say it again. When you're only working with less than 250 cubic inches it is much easier to build a pooch than it is to build a rocket. Too much cam and you'll end up with a motor with less power than stock. Not enough cam and you're leaving horsepower on the table.
