340 tunnel ram

The reason tunnel rams have a bad rep is that they were very popular at one time, and on PARTICULAR motors they run like crazy. Other motors actually suffered from them. I blame this all on Car Craft magazine. Coming from the Pontiac camp many years ago, I can tell you that a tunnel ram on a hard pulling GTO 400 will cause it to turn into a slug. Progressive Tri-power was a better system than dual 4s for those motors.
