My Raptor is quickly approaching the 100K mile mark and instead of getting a new truck, I'm thinking of freshening up the motor with a rebuild, maybe adding a little horsepower (500 RWHP goal), and getting the transmission gone through as well. Both the interior and exterior are still in great shape so I see no need in shelling out big bucks for another truck, especially since I'm also in the market for a '13/'14 GT500. I'm interested in forum member feedback from those that have gotten a rebuild/new motor from Livernois, Hennessey, and some of the other aftermarket companies that deal with Raptors. I'm also interested in feedback from those aftermarket companies to answer the following questions: 1. Expected amount of downtime to perform a motor and trans rebuild. 2. Ballpark cost figure...not looking to build something to win the Baja 1000...just a nice build that will last me another 100K with some added horsepower. 3. Warranty information.
