I'd look up the original ACDelco filter specs for the one that applies to that engine and see if it contains an anti-drainback valve (ADV) and a pressure relief valve. If so, make sure the substitute meets the same specs. Personally I don't trust the ADV in the WIX as the one I used on my Rambler let it rattle like crazy on start up. Problem cured when I put on an equivalent ACDelco. After watching a video on Fram filters I wouldn't use their lower end extra guard but the Tough guard apparently is built to higher specs.
