Yes John, it's lowered a couple of inches. Also, the rear springs are soft so it squats quite a bit on the launch. I'm going to keep a set of 28 x 10 QTP's on the salad shooters for when I go to a 1/4 mile. Honestly, that's only once or twice a year. I have no converter slippage as I lock the converter at the 1/8th mile mark for a little extra oomph out the end. 7000 RPM should get me right at 130 MPH figuring in .5" for tire growth at 130 MPH. Rev limiter is set at 7200 so I've got a teeny bit of RPM room to grow if need be. I don't expect to trap over 130 with just TFK LS6 heads and a Vindicator cam. Might fool me but, if so, I'll gladly drop back to 4.30 or even 4.10 gears. I'd like to have to do that.
On the gear selection, I already had the 4.56's as that's what was in the big tire Firebird when I bought it. I switched those out for 5.38's as the Firebird is my 1/8th mile only ride.
Thanks for the input guys. I'm going to get another set of 26 x 10's for now. I briefly considered the 28 x 9 M/T's @ 27.3" tall but I think the top end biased engine combo I have will like all the gear I can throw at it. I'll post up results as soon as I hit the track.
*EDIT* OK, just got off the phone with Summit. My tires are leaving tonight so I'll have them either Thursday or Friday. This car should leave like the proverbial scalded jackass now if the tires will hold it. 1.3x 60's here I come.
