when i was in college in the 60's I had an impala just like this one. I had a 400 Pontiac engine in it. I have no idea how fast it would go. I lost my nerve around 110 and it was still pulling. My dad had it crushed in the 70's
Nice car I have three of this wonderful impalas in Fort Worth Texas and they are not for sale!!!!!!!!!!!!!!!!!!!!!!! viva the 61 impala bubble top the best year ever made.
