???? Exactly the opposite is true. Tall tunnel rams poking sky high through the hood do not make good torque and bottom end. Even the description on Weiand's High-Ram tunnel ram (which is the one you referenced that Summit and Jeg's use in their combos) says, "NOTE: Due to lack of low-rpm torque, not recommended for everyday street use."
Generally speaking, the higher you raise the carb with an open plenum, the more you push the power band upward and kill off low-end torque. This is true with carb spacers and intake manifolds. Why do you think the low-rise dual plane Edelbrock Performer is designed for low rpm torque and the high-rise single plane Victor Jr. is designed for higher rpm HP? A tunnel ram is even taller than the Victor Jr. pushing the power band even higher.
The street cars I've encountered with tunnel rams are typically over-carbed and make no low-end torque. That's why I said on the other thread that you would get smoked red light to red light on a regular basis. On a Friday night, we used to go looking for street cars with tunnel rams to race. We used to refer to them as... All show and no go!
