Actually a well set up tunnel ram doesnt kill low end torque that much. It actually should add a good bit of mid range torque. The down side to the tunnel ram is that there is so much metal to get heated up before the engine will idle properly and not want to run lean. With any tunnel ram,the secret is to run the minimum plenum volume possible that doenst hurt power. I have toyed around with the idea of replacing the single 1150 on my engine with a pair of 660's. I have some ideas on how I would like to build a cutom bolt on top for the plenum that would allow me to reduce the plenum volume alot and then add some super sucker type carbs spacers to imporove the signal to the carbs. In any car with over a 3500 stall covertor you could almost certainly pick up soome power everywhere with a tunnel ram. The real secret to how it works is that if it is designed right it will alow you to put substantially more carb on the engine will still getting a good signal to the carb and get good mid range response while still getting the benefit of the extra carb area at the top end.
