I guess an easy way to settle this is put the darn motor in a school bus, rip away all you want, if you want to make 700 horse go for it, i dont see how your gonna make this a daily driver no matter what though, it will be a no nonsense race car with that kind of power, plus always remember, things look good on paper but its not always that way. What do you plan on putting this in, what is the torque curve? how do you really ease into a motor if your putting out 500 ft lbs at 2500 rpms? Just all things to consider, but all in all i guess the more horse the better huh? Sounds like a killer motor, anyone would love to have it but If you have the money and are really serious then you have your mind made up, what else do you need? besides a really strong driveline???
