Work great. I have 3 guys running them and one of them is on his 3rd season with his in a 408. Crank has 45 nights on it and still looks and works like new. Been turning it 6700 in a 2950lb IMCA stock car.
The two other guys just switched over to them because they had been running the cheaper Eagle cranks....they spider cracked after 15 nights on the rod journals.
