Paul is right... That is a little over doing it unless this is a strictly race car. If you wont be racing this car every weekend then it's a waste.... 700 HP is a TON of power!!! There is the 514 crate motor for around 7-8 grand and it has 625 HP. 700 HP would be VERY hard to get out of just a 460 unless you had THOUSANDS of dollars into it. Then what about the transmission? You better be running a full on race C6 or something with that kind of power. Then what about the rear end? 28 or 31 spline axles and stock gears wont handle or cut that.... You will need a race rear end too. Then what about the chassis? See, the list goes on and on. I think you should try looking at around 400-450 HP out of a naturally aspirated 460 and then have a fairly built C6 and 31 spline axles. Much simpler that way IMO.
