How to ruin a classic muscle car era Mopar
As far as modern engines go that's a topic that's been beat to death. They made big hp and went 9s on junk tires/suspension (compared to technology now) in the early 70' so shouldn't we at least be where we are at today?. Should we have more refined stuff some 30+ years later?, well yes, and if you look at where performance was over 30 years ago we are way behind.
I heard somewhere that all the truly big break through innovations in performance were long ago, all we have done since is refine what was already there. I think that goes for allot of thing's in life, the Apollo 11 landed on the moon with a computer less powerful than my phone, and my phone can't even function properly most days.
As far as building cars build whatever you want, just don't get offended when other people think its ugly.
