What year is the 235? If there's a big oil gallery running between the lifters, hydraulics can be run, but the cam and lifters MUST match. Hydraulic cams have a different profile, and completely different acceleration ramps than solid-lifter cams. If you're buying a new cam it's absolutely imperative to run new lifters with it. NEVER put used lifters on a new cam, and ALWAYS run the correct lifter for the cam. Solids and hydraulics cannot be swapped!
