I'm at a loss, I've looked at most all referred to web-sites, and a lot of past forums, but I just can't narrow down the engine stamp to my 1952-3100. Please see attached photo. I think the engine is stock to my truck, but I was looking to confirm. I think (based on data found here on SB), that it's a 216 cu in. What say you? Stamped code is " BKCA769609"
