Got home after dark, so too late to take engine or transmission pictures. I will get some when I get the opportunity. I am sure it is a 402 bbc. I will also check the linkage, The whole issue may be there. It is hard to get into park and out, so definitely a possibility.
Also there is a chance carb needs adjusted. It does start right up, but idles a bit rough. Plan on spending some time on it this weekend. Also trying to clear a space for it in the garage. Would be nice to work on it in all weather(or at night).

Thanks all for your information.
