SBM Edelbrock/Speedmaster Head Data

I love the perseverance!!
You’re solidly above 300 now.

Any idea what the current runner volume is?
Width at the pinch?

We’re on the same page WRT the pinch/ssr relationship, especially with milder efforts(which is why I advocate for getting after the ssr early on in the porting process).
Port volume for the 50 deg test was 196cc. It would have been around 192cc for the 45 deg test.
