Open chamber Edelbrock head this time
I’ve brought this up before and did not get a response. I’m far from knowledgeable on the subject but I’m a big follower of your work.
So… it is my understanding that opening the pushrod pinch has little gains compared to the sum of all of your other port modifications. Ha, spell check just corrected “port” to ”poetry”. Not far off.
ANYWAY, I would like to see the results from maxing the ”pinch“ but, instead of matching the intake to the as cast port, I have to wonder what would happen if the area from the pinch to the port entrance was straightened with a matching intake manifold port, effectively straightening that part of the air intake instead of the hour glass shape that area creates.
