Crate motor and tranny

I have a 73 mustang that will one day get a proper restoration, it has a 351C and an automatic. I plan on upgrading to a 351 based stroker with a Lentech AOD, these plans are on the back burner as my wife just had twins in January. But I was BSing with my father and he is in the late stages of a 66 F100 rebuild, that he enjoyed and he has just purchased two more 66's that he thinks he can part together to make another nice one. Anyway I told him what my longterm someday plans are for my car and how I really thought the performance and reliability of a crate motor were the way to go, so he asked me to take a quick look into it and see what I could find out.

I am really impressed with the literature on Lentech's tranny's but don't know where to search for an engine.

Any help would be very nice.

Thank you.
