That was my first car I beat it to death. I would change it over to 4 barrel the problem with the 2 barrel is it hesitates. Engine will run much smoother with the 4. I was 17 when I had mine these cars move. I had 400 2 barrel it hesitated but you had to hit right to loose that hesitation. I would look for trouble in that car. I would race who ever found willing to. My friend had a 68 396 Caprice he could never catch me in that car, i beat out a Saab Turbo at short distance with it I would eat 460 Lincolns for breakfast and Cadillacs. I have pinned the speedometer with room I had my foot down not even 3/4 of the way. i might of had 323 in the rear. I had a 69 newport 383 4 and 73 was a faster car. I just bought a Navajo 73 Newport coupe all original 78,000 mi and it was in a climate controlled garage all its life. That car I'am not going to mess around with I will keep it stock and keep the 2 barrel. I 'am sure its a Carter carb you have
That my 73 Imperial I can kick myself for that sale but I more then doubled my profit. You could see my 69 Newport in the background
