[QUOTE="MVanover, post: 1049870, member: 75690"] If I had a OHC 4.0L go sour, I'd consider replacing it with the pushrod version. My son pulled a 4.0L out of an Aerostar and built up the engine with new forged pistons, aftermarket cam and heads and JB headers. Then dumped it in his Bronco II. I think it has more power than my 4.6 L V-8. He did rework the rocker arms with stainless steel cups and block off the arm's oil galley to force oil to the push rod top. Very strong engine and has lasted for 20+ years and still going strong. [/QUOTE]
