Not a 235, but my beloved '55 has the original 265. It got pulled for a knock (cracked piston skirt) and will br the engine that powers that truck for years to come. If the truck had come with a six, I would say the same thing. I'm rebuilding my own, as that is my skillset and my preference. Everyone has their own with both. If something more powerful than what your truck was available with makes you happy, then by all means, go for it. I know a guy with a Chrysler 440 in a '57 Lincoln. It's odd, but it makes him happy.
