If you can tell me the size of your 2.7's runner openings I can compare that to a extra 3.2L I have.
I got them mounted on already so I won't be able to give you the measurements. I thought the 2.7 and 3.2 were identical manifolds.

Jack Raby had made this quote on another thread: "That 2.7 intake is killing the potential of that engine. The 2.7 intake is inadequate even for a 2.7 engine."
