I will gather all that info later today, I have already researched the casting number and it is indeed a 66 283 engine, but thats as far as I have gone, I will try to get a better shot of that area, specifically that freeze plug, the photo is actually not as convincing as it is in person. there really is quite a bit of what appears to be alpine green in multiple "hidden" places on the engine.
