Holley sytemax

What is the throttle body bore diameter for the Holley systemax intake?

I'm 90% sure it's 75mm... I just checked summit racings website, and the manifold doesn't have a a throttle body bore listed...
As far as i know, the Systemax and TrickFlows street/track heat manifolds are both 75mm.

I thought it might be 75mm but I'm not sure. I looked everywhere I could think of and can't find it. The throttle body gasket that summit has as a suggest part is for 70mm.

Weird..

My buddies systemax is 75mm. He measured cause he was unsure what size accufab TB he should get.
