Yes, tested the out-of-the-box Edelbrock castings. I presume it was the XE cam.
I added the link to the article in my post above.
A fwiw tidbit....
Many years ago my previous engine builder put together a 4.250 stroke for a friend using the Edelbrock round port 215cc runner volume heads.. No port work other than a cleanup.
Performer RPM intake with a vacuum secondary 750 Holley and headers. Cam was a small Crower HFT with 236 degrees intake duration.
On the dyno at the start of the pull it made 499.4 ft.lbs. torque at 3400 rpm.
At peak tq rpm it was 570.7 ft.lbs. and carried over 500 ft.lbs up to 5300 rpm.
