There isnt anything wrong with a 4dr man. I would love to find an early 60s 4dr Impala or Bel-Air and make it into a screamer. Lower it and suicide the rear doors, throw in a big block and back it with a clutch. Just cause its a 4 door doesnt mean its slow either. There was an article in Mopar Action I believe where back in 66 there was two 426 hemi 4 door cars built. So by no means does a 4 door mean slow or ugly. Just something new to the table. Build it to your dreams and let the good times roll!
