I would say Teague 1000, Peto 920, PFaff, GT or someone else reputable that will build you a 1000+ hp motor; I think it will take that much to turn those numbers...Talk to Infomaniac on this board for advice on that big of a motor. Also, the lowest drive I would go with for that horsepower would be the Imco 4x4, or if you are dripping money go with the Merc #6 and be a little safer..Good luck, and don't forget the Lifeline vest..
