Tunnel Wedge BBM / TFS Comparison
« on: December 30, 2022, 12:01:55 PM »
Has anyone compared these two intake manifolds for:
a. flow
b. overall fit, finish, machining

Which unit do you prefer, or is the choice a coin toss?

It is my understanding that the BBM is slightly larger in side and port dimension than the TF or Dove or original. It was everyone's assessment before that the BBM would be better suited for a larger displacement ove a smaller , and the TF on smaller engines as cast. The plenum area is larger on the BBM as well.

Been wondering about these two intakes lately too. How about CCs for either?
