400's are they any good?

Additionally, correct me if I'm wrong but, I read from a magazine that one of the reason's the 400s and 440s were kept around through the late 70s was because Chrysler Corp was going to build a "Ball Stud" Hemi off them but, due to regulations and financial pressures the idea was scrapped but, also it is one of the reasons the 400 was also built with a thicker webbing in the block in mind.

Sure enough...

Damn, that's interesting! What could've been...

As I understood it, before reading the write up, which IMO, is incorrect to a degree from other material I have read...... The big blocks were kept mostly due to NOT having a replacement and used until there need/demand dropped badly with no doubt, cause from emissions standards and what they had to do in order to keep it legal.

My '78 P code 400 was what? A whooping 190 - 210 HP or some crazy tihng like that.
