THANKS for the info. I need 1 5/8 or 1 3/4 primary tube size and more length in the tubes to optimize the torque out of the combo that I will be putting together.
The 1 3/4 might be needed if I decide to go with the larger of three cams that I have selected....in order to make power in the 6500 rpm range.
Those would be a sweet header though....
