I daily drive on my ProCharged GT with 473 RWHP and 4.10s. The top end of first gear is kind of useless on the street, but otherwise it's nice. I imagine with 26" tires you will be right at the 6250 rev limiter in the 1/4 mile. I haven't taken mine to the track yet with the new blower, so I haven't gotten to try it yet. The math says that with my 26.3" slicks and 6050 rev limiter I should be good for 115 mph, but that doesn't account for tire growth. I think it's going to need a little more, but we'll find out soon enough.
