Dear Mr Lee;
NO, NO & NO.
The 216" engines were 80-90 Hp. and worked just fine to get everyone around the country for three decades. After the Korean War the 235/261 engines replaced them with 100-140 Hp. and are quite different.
Some have made Hot Rod engines out of them in the 1950(s) and still do today (myself included)
with some sucess. Even then 5500 RPM is about tops safely.
To 'supercharge' wouldn't do much at those speeds, but "Hot Roders" are a 'strange breed of cat'.
