Go with the 305. That's about the widest you'll be able to go on base wheels. You might think about going widebody on the rears, though, as 700 HP is more than base wheels are able to handle. Typically, anything over 600 HP requires widebody sizes to stick with any success.

This, from Unreal, who has 1,200 RWHP...
I'd read up on tires on the FI section. Much discussion...
PSS are not straight line tires and don't hook >600rwhp.
Width is FAR overrated.
NT01 is a road race tire, not a straight line tire.
Just about no one runs "slicks" on a vette. They don't even over 18" drag slicks, just road race ones.
R888s are ok, but noisey, don't last long, but can hook ~600rwhp. For your power level you probably want a ET street SS or NT05R.
NT05 and NT05R are two completely different tires. One is a drag radial, the other is a performance radial. Not even comparable tires.

I just picked up a set of Mickey Thompson et streets 275/40/17 on some aftermarket C6 Z06 rep wheels 17x9.5 I think. I'm going to try them out in a couple weeks at the track.
As for the widebody, go OEM. I did the RPI prepainted and regret it. Fitment is not that great. Holes all need to be drilled or dremmiled out. Paint had runs and drips in it. Poor quality.

the 275 or 295x17 on cars that make 650+rwhp will both get you in the 9's with a 1.45 60ft or better on a narrow body.I have the 305's to try next.you wont need the wide body

You probably won't like this, but my opinion is that you should not be street-racing a 700 rwhp car. I know...almost all of us have done it, but you "street race a lot". It is only a matter of time before you kill yourself, or someone else.
Enough of the sermon...I don't think wider will do you much good, even with a wide body. Taller tires are possibly going to be better for you. Once size taller increases your footprint more than one size wider. It will also give you a slightly lower (numerically) rear end ratio, which will reduce your spin off the line, and increase your top end a bit.
I still hope that you think about it a bit, and take your really serious racing to the track.
good luck.
