Well I had it on there with my stocker ported cylinders and loved it, it launches in 2nd great, 3rd hits really hard, rarely get out of 5th gear. That's why I was wondering why so many people run such big front sprockets. I'm gonna try stock gearing when I get a new chain and see how I like it. I'm hopin it'll keep the front end from comin up some and spread the gears out a little bit.
