Blow IT!
 

It is only natural to become super natural since you dropped the weight with the all aluminum block, you should balance that out with the blower mounted on the head. Really, it makes sense.

You get the "wow" factor under the hood
You get the schweet blower sound when you nail the throttle and bang the gears
You get the added bragging rights
You get the extra power, all the time.

You know you want it...now hurry up and get it on there!

spray
 

I think it was last year that a blue Z06 won the One lap of America race. the car had a 427 LS1 with spray. I believe it(spray) was used on the drag portions, top end runs and maybe long staights on the road coarse.

To your question...NA with spray and a progressive controller. I am thinking 700 is going to be plenty for all of the above reasons and you car is going to have the "Wow" factor from the way you are building it.

Since asked for an opinion.. You said in a world of 1000 hp cars, it needs to have it. Well, your car is so out of the ordinary & ahead in so many other areas I wouldn't worry about it, besides when will you ever be able to use it all? The car will handle so much better w/out the extra weight up front, not to mention how much cleaner it will look. Not sure what kind of intake you are using, but a fabbed Sheet Metal Intake would look killer. But then again I'm kinda partial to them. :D Either way..The car is amazing & can't wait to see at SEMA.

Done deal. it will be a All Aluminum 540, N/A motor. Should be 750HP no problem, maybe more depending on how nice the heads come out. Still trying to work out the nitrous, but even without, it will be awesome.

Thanks for the opinions and compliments. Let's see if it can live up to the hype.

Sounds awesome to me. You won't be sorry with that choice. Throw on some AFR 335 CNC'd heads and AWAY you go!! Those should be able to feed that sucker.
