From the research I've done, the after numbers should be hi 90's HP and lo-mid 100's tq. I've read some good things about the SE255 cams.

Doing some headwork to boot should get you a good performing machine. Good luck. You can try google. Also, check out the Latus HD forum. Lots of good info there. The guy who runs it, Mike, is super knowledgable.

Check it here (I found it using "tw6 dyno" as the search criteria):
