Brent ... since this thread has already drifted .... go to Speedtalk and look up the thread "Why an engine makes more power off a burr finish" .... all 58 pages , back on 11/20/14 . Lots of good info , photos and hard test data .
Makes for good reading when it`s 1 degree out there .... 17 here in SC .
