Big cube block, Big heads, big solid roller, and some nitrous or forced induction. 
TPI421, Rcklessdriver are a couple forum members who I can think of right off, that have about that power level.

A few here at that level a lot more educated than me.
The engine is not a big deal if you have the supporting parts on the car.
A c4 was never intended for 700hp. Trans, rear end, and maybe suspension, and brakes should be considered if not addressed too.
It starts to add up quickly to build a c4 right. If you plan to make 700hp and drop it in... Good luck.
IMO at that level you need an LS block if not aftermarket motor. If those are not an option, I'd say 383-396 stroker is usually 500+hp built decent on the LT platform, or build the motor for boost.
If you have not been in a c4 with 500+ hp, maybe try that first. You might be surprised, plus 500hp will still move away from other cars quickly.
Don't forget tuning is an issue too.
If you have a lot of money, determination, and patience to have a 700hp c4 enjoy it.
IMO the best route is to sell the c4 and get a newer better more powerful car, or if you like a raw driving experience sell the c4 and get an AC cobra with power.

How about a turbo with about 15 pounds of boost? At that level you'll need to add some ring end gap.
And what does the rear view mirror have to do with it? Or are you talking about not doing wheelies everywhere?

Nitrous is not my favorite way to build power. My old NX system made more power on a full bottle than it did a half full bottle. Can you imagine how annoying itd be if you made more power on a full tank of gas vs anything less than full ? Well thats nitrous.
and heres the part the internet forum geniuses cant comprehend. This is true even when i was using a bottle heater to heat the bottle to the same PSI when it was half full as it was when it was full.
forced induction is sooo much better.
I see people make mistake of building a high compression motor figuring they can spray nitrous, and that limits its ability to be good for forced induction.
im not saying build a dog 9.0:1 motor thats going to be sluggish at anything not in boost (which is where you drive it 99% of the time you prob arent in boost), but pick something like 10:1 compression not these 12:1 motors...
mild boost, cam, heads, 383 , headers will get you there.
if $$ is an issue build the bottom end knowing you will want to add boost.

Trade it in along with your engine rebuild money for down payment on a NEW 2019 ZR1

c4 is the better car vs all the electro nannies of the c7. Its not as ‘raw’ of an experience as the c4 - which todays buyers dont want. They want a car you can fit golf bags in and doesnt ride too harsh ‘sloshes soda on drive to palm springs’.
The top speed and track times look good on paper but Both cars performance potential is unusable on the street.
and at the dragstrip, lets say ive seen many a new corvette owner get frustrated it wont hit the times the magazines say it will - even seeing a frustrated rich new corvette owner give up and let some local redneck drive his car to a better drag time bc he knows how to.
so to me, one vs the others makes no difference.
I get motion sick easily (make fun of me). Either one is gonna make me puke if pushed to its limits

I was thinking of getting the 396 turnkey but I may go with the texas speed 421. I like it the way it is but my old c2 had a lot more top end I'm not trading my car if I get another I'll just buy it. The c4 handles better than the c2 but that big block top end I miss you know scary fast

I agree, you got some real douchebag answers. Not everyone on here is like that, obviously.
I have always been puzzled watching shows like Engine Masters when they go and build a VERY basic small block and throw it on the dyno...BAM....400+ hp. LT1 is a fuel injected "high performance" engine in a sports car and its only 300hp ?!
Id like 500hp but am learning the amount of supporting hardware is very expensive. Camry's make 300hp these days and my Vette trans and diff can't handle much more than 300hp?
Keep us posted on the build, I'm interested. (Though I think 700 is over the chassis engineering capabilities and safety)

x2 tpi421vette rklessdriver and a few others have done it, wait for them to chime in if you want an NA SBC
If you can make it easy, go for big cubes right off the bat. Its just more reliable, not hard to make that # at all these days with the parts available. RPM adds up real fast $$ with cubes youll need less to do the same thing.

They make a 620hp version that has a hydraulic roller and lives on the street. Bet a nice port job on the heads/intake could get you to 650+easy with no loss of reliability. How much can you hook up anyways?
Need to run 9s? 10s, 11s?

Ed Wright was into the 9's in a LT-4 equipped F-Body N/A. 383, solid roller cam, ported heads and compression. Don't know what kind of dyno number it put together but that's up there for fast without going to an aftermarket block or forced induction.
