Thanks for the info, that is good to know. I guess the opening on the 70mm (Edelbrock)TB is bigger than 70mm.JoeDirte said:I measured (this is the O.D. & I.D. for the outlet of it only):
O.D. 3.050" = 77.47mm
I.D. 2.975" = 75.565mm
If you want I can measure the inlet opening but I would have to guess that the I.D. should be the same for both.
