Just baught a 53 3600 last weekend and was told the it had a 235 swapped into it. when I got home upon further inspection it doesn't resemble what I thought the 235s should look like. The valve cover has 6 bolts holding it down (3 per side) and the radiator support was modified (poorly I might add)to further complicate things the model numbers don't match anything I can find on the site. I'm sure this has been addressed before however none of the articles in the tech tips or faqs cleared things up for me. I'm hopping someone can shed some light on this..
