I could never identify the one I have in there now. I love the stall but its way too loose. Its like driving a car with the tranny slipping all the time. I had a Mopar performance one that i chewed the gear up on when my MSD digital 6 took a dump. The timing went crazy and it kicked back and broke the starter and took a few teeth of of it. It was a little too low stall and kinda tight.
