Is about 500 rwhp/600fwhp possible NA?

What do you consider driveable? Some thing making 500 at the wheels na, is going to a fairly wicked motor. With a HYD roller cam car, it could happen. It would take a lot of cubes, with a lot of compresion, very well worked AFR heads and a cam that is large and designed to work with the heads. It would also take a lot of header as well. The intake manifold would have to be well worked with a monoblade or some thing of the like. It can be done, but I wouldnt drive it a 100 miles a day in traffic.

Just about anything is possible if you're got more money than you know what to do with, but it's easier to build a 400 rwhp NA stroker and add a hundred shot of N2O. Doing it that way it would be infinitely more driveable as well as more budget friendly.

Turbo/Super/Juice are the only ways you are gonna drive a motor producing that much HP daily. Just because you can control the amount of power you get, actually delete the super, a turbo or juiced car with 1000+ hp can be driven daily and is very tame, but not an NA motor, if its even possible with an LT1 (lt1 meaning LT1 heads/LT1 intake)

Someone agrees with me!! Ha ha, I've got em fooled now...
If you haven't already killed your stock LT1, invest in a supercharger and call it a day. As long as you keep the boost levels reasonable it should last for a while and easily make 400 rwhp. Plus you can add it to a stroker and get your 500 rwhp in the future. The biggest benifit being that you don't have to constantly refill bottles.

Get rid of the stock heads. Period. Or anything like them. There's already a few members on this board who have broken 550rwhp with the LT1. But they had heads radically different than what you'd bolt on.
Mindgame hit 568rwhp on a NA 383 with about 11:1 compression using pump gas(solid roller and LT4 intake). And he said it idles about like a CC306 in a 350. But he has converted GenI heads. Jim hit 647 crank hp using RR 23* AFRs and custom intake. Both are "street" machines, if you will. And one member has SB2.2s on his LT1...I wonder what that one will do (said to make near 700rwhp when done ) .There are a couple more that did it, but they don't say much about it.
500rwhp NA is plenty possible on our cars. It just depends on the route you choose to take to get there. Better heads are a MUST though so get ready to put up some $$$. And a solid roller might be a must, not too sure as hyd rollers are getting a lot better.
