Not really sure where to start, need help..

In post #3, you said you plan to pull the slant out and sell it. Before you put too much labor into it, realize that many here couldn't even give away a perfectly running slant & tranny for over a year, so took them to the dump. That is good for us that stay slant, but not for you. You would be real lucky to get $200 for the engine & tranny if running well, and maybe $100 as is, so decide if worth your time.
