Advances timing 6 degrees for more low end torque and a snappier throttle response. Works great with aftermarket Rev Boxes too. Not recommended with Big Bore Motor or hi-compression pistons.
I just pulled mine out today. Was installed less than a year. I still have the original installation instructions, and fly wheel puller, and 6 degree key if somebody wants it. I'm going with a a hi-comp piston and it's not recommended. I paid $22.00 shipped. I'll sell it for $12.00 shipped if anyones interested. PM if you want it. I'll take Paypal or Money Order as payment.
Here's a link to an article on this website that has more of a description and installation guide (with pictures).
