I am also thinking of changing the cam on my car. It was givin to me by my brother. He bought a 68 camaro that was used for the strip, but street legal. He pulled the engine and tranny and installed it in this Nova (Camaro body very rusted).
The engine has a very radical idle(sounds like popcorn poping). I don't know the specs but I feel bad for the cars behind me at the stop light because of the exhaust fumes are very strong (smells like gas). I just want a low rumble at idle without the bad gas smell. What cam & converter would you recommend? What converter would also be good for my existing 350 and reuse on my 454?
