Hey an even better deal is the 520/570 kit n motion has produced. Basically a bolt on kit (520) with simple case modifications. Kit includes cylinder (no core charge), piston and gaskets. Looks like it costs around 995.00. Pretty decent price compared to what I've seen out there, not to mention you then have two cylinders. check out the website, nmotiontechnology.com

smok3d-The 450 r that you described sounds like one that i raced in florence a few weeks back and it was keeping right up with my 690 raptor at our comp hill. That 450 0r (480) so far is the only one to hang with me but more are getting closer all the time.I was not initially impressed with the 450 r but after seeing how they can run with either a big bore or pipe and cam i must admit they can perform very well.
