Is 600 hp too much? - yup.

Is 600 hp too much? - nope.

Are you experienced Cobra drivers (and I use that term loosely) really going to tell a guy who's not there yet that this is a practical idea?

Can you keep it straight? - sure, no sweat at all. Will you have wheelspin issues? - do you really have any doubt about this? Can you put it all to the ground, all at once? - probably, with the right setup. Then again, probably not with what you will likely wind up with.

Do yourself a favor. Think about this. Have you ever been behind 600 hp before? - got any idea what it really is like? Put it into a 40+-year-old design and what do you THINK is going to be the result?

IF you're prudent, and want to stay alive, you'll be good with it for a while. Get careless or smug about it and you will die the first time you apply a bit too much pressure to the gas pedal as you arc around that onramp corner. Forgiveness is not an element of a Cobra. There is zero crash protection. Tires will take only so much stress before they cannot hold on. And since you're much more likely to be driving this thing on the street than on any racetrack, where you have at least a chance of not running into anything immobile like curbs or abutments or poles, your chances of surviving that first f*ckup intact are amazingly slight.

Start with a 350 or 400 hp motor and see how much you really have to learn. Once you've honestly comfortable with that, then 600 hp will be OK for you - and you will survive it since you will understand just how easy it is to get in over your head.
