Here's the issue with the recommendation on cam site...
What size engine is it going in!
Put that cam in a 273 and you'll need a 4K converter, put it in a 408-416 and you could run a stock-2500.
What your intended use is will also play a part. If mileage is a concern, it's going to require a tighter cruise set up. Full out racing, like wheelsup suggested.
A good converter is worth every dollar you spend. It's also the one place most people skimp...
