Howards vs Hughes vs Lunati Camshaft

If the Lunati cam in your Duster is good, it should work fine as long as you match the lifters back the way they are now. If you use the other cam, you will need better springs, Morel hydraulic roller lifters, custom push rods and adjustable rockers. If the Lunati is good to go, it will save you a wad of money!
