So I had to ask him a question about his horsepower claims. Not sure why it didn't show up on the ebay auction but this is my question and his answer.....
I was wondering about the HP. You are very specific about the horsepower, however you gave two different numbers. First you stated 713 HP then 608 HP. Which is it? And how do you know? Have you had it on a dyno? Thanks.
First is crank. On description i put RWHP. I was wrong on rwhp, i had looked it up for other buyers that had questions. Hp is always most important. Its 598 at the wheels.i had it dynoed prior to tranny rebuild and lift pump , and prior to built tranny" tune".Before it was 461. There is a youtube vid of my set up EXACTLY. Dyno was also done in florida bout 3.5 hours from me. Florida has horrible air density for power. I used to live in south carolina and had a superchared car and lost like 9 percent on pulls. Truck has the " built" tranny tune by Nick P. at duramaxtuner.com, and egr block, air dog 2, suncoast fully built trans and billet 1056 conv built by pelamotorports in jupiter fl.
So, that cleared that up. It was 461HP, now its 598HP....which clearly explains why he listed it at 608HP and 713HP. :dontknow::screwy:
