That was a nice video. If your a Pontiac fan of that time period, it is hard to find fault with anything that was said in the video. Having owned 3 421's from that period, I agree the street versions are among the very best V 8's from any manufacturer, period. They are extremely smooth with a fluid power flow as he described. Especially with a turbo 400 transmission. From 600 RPM to 5200 RPM, the torque is huge and never drops off. Extremely reliable as well. The difference between a 389 and 421 is hard to describe, but huge. Just much more of everything a 389 has to offer. 32 extra cubic inches feels like 100. 428's have a very similar feeling to me. 455's seem to work hard to make power compared to these ultra premium power plants. Great engines!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
