If you think the 3.8 MB V8 has the same power as a slant six, then you have clearly never driven a 3.8.
Thanks for the great post. I agree, with just a little effort, the 3.8 could be put in great shape. IMHO it would be much less effort/expense than swapping in an engine of a simple, 48 year old design.
If I read your post correctly, you believe that a BB Chevy will bolt to an MB auto transmission? Forget it. Even if it did, the transmissions life could be measured in milliseconds.
Have a great day,
