Hi All, I'm wondering if anyone has any tips/advice for my stepdad for his 67 Fury II with a 440 Super Commando. It's no regular 440 either. That's for another time. Anyway, the car now has a Demon Carb, and TTI headers that came with the exhaust "kit". When the car is cold, it runs like a bat out of hell. It can do burnouts and runs pretty good. But when it gets hot, it does not want to run, and when it's at a stoplight it stalls. My stepdad mostly uses Edelbrock. So the intake got changed from a performer to a regular rpm. Mind you he put an aluminum radiator and electric fans in it too. He did a compression test and checked parts of the engine, and he thought everything looks fine. Since he got so disgusted with it, he just stopped working on it. Now it just sits and collects dust. Since he did a resto, he drove it a little over 200 miles. What could it be, gas tank? Any help would be appreciated. Thanks.
