Early A V8 swap advice

As to dropping the chassis down over everything; I did that once. I even built a nice support work for the engine/ tranny/K/suspension unit. But once was almost enough for me.
I used to take out the HO 360 every September long, and swap in a mellow 318 for the winter. Then on May long, back in went the 360. So I tried it a second time, but that was it, no more. This went on for about 5 years. Then I finally started makinh bnetter money and was able to buy a winter beater.Plus
I would take the 360 apart every winter to see if anything was amiss. And I caught a few things that couldda been expensive. But by the fourth winter the engine was hanging tuff so this was getting to be old news. After that the engine stayed in there. I think the last time out mightta been 2005. It now has over 100,000 miles on it, since it's maiden voyage in 1999.
So, to recap; I'm not a fan of chassis down. And yes I had a 2-post hoist.And line-up pins made.

If I was gonna do all that again, I might just make the top piece of the core-support removeable, for the little work it saves.
