Over the years there has been a lot of claims about modified 6.9's from video with Dan's
http://www.youtube.com/watch?v=BxN4AQNzFYE . Which I believe was never completed as owner is in bad health . But no dyno results to verify power. Other cars the same. At this point I believe I am only one to post dyno results which is currently 255.6hp at the rear wheels. Car will be going in for head work in next few weeks. And will fit cams and cam sprockets and 560 throttle will be fitted...
