No people, a one inch open spacer is not a 1 inch open spacer. Did anyone watch the videos ?
This spacer right here is a type of a 1 inch open spacer. And it made almost 30 ft lbs more torque than another spacer.
Myself, I took my 1" Super Sucker of my old 455 HO. It had a Warrior. I have tested a few intakes and carbs at the drag strip. When I put my old Moroso plastic 1" open spacer I lost most of a tenth in ET and it was aluminum. Did nothing for the heat transfer.
This Polymer Racing 1" spacer made the extra torque upside down in the tests.
