Secondly, it also depends on your proficiency. Since we don’t do this job regularly like the pros, it would take us more man-hours than the projected 40~65 man-hour. I made a time-motion study of a couple engine rebuilds I did in the past and accumulated 70 man-hour total on the worksheets over a period of several weeks.
Another experiment I did was to determine how long it would take me to assemble a 911 engine using pre-cleaned and ready to install engine parts. All parts were pre-checked and inspected prior to assembly. I did three (3) separate runs in a span of 2 weeks and were able to complete the assembly under 8 man-hours. At a leisurely pace, 12 man-hours is easy.
For me, it is not how fast you completed the rebuild but how well you did the job at your own pace. Who cares if you are slower than John Doe and takes longer time to get to the finish line? For me, it is all about enjoyment and satisfaction.

I agree. What I wanted to know was the real world timeline, with life included...
I suspect many folks think they can rebuild a motor, in the real world, in 3-6 months. It’s just unlikely...
Life, has a way of intervening...
