There was a guy that had a 73 Fury,he said it was a Police car before he bought it. He had it painted black with a nicely done flame paint job on it,it was a nice car. I had a Weiand Tunnel ram setup for a 440,with two Holley 660 carbs and air cleaners. I asked him if he wanted to buy it,he said it wouldn't fit his 440. I said it would fit,he insisted it wouldn't fit,because he tried to put an aluminum intake manifold on it,and it fell right into the valley. I told him that he tried to put a B engine intake on an RB engine,and that's why it wouldn't fit. He said he was sure it was a 440 intake,and that his 440 was bigger than my 440 because it was a Police Interceptor 440,and they are bigger! I couldn't convince him otherwise! I still laugh about it to this day!
