Changes done and ready for the track.

The most recent phase of changes are done and I'm ready to get my 1975 Duster to the track. Current setup:
1973 340 .060 over 10.5-1 comp
KB pop up 340 pistons
Comp Cams XS282S solid cam .520/.540
Eddy aluminum open chamber heads, mild porting and cleanup
Eddy RPM Air Gap intake
Holley 750 DP
MSD Ignition
TTI headers w/X pipe and 3" exhaust out the back w/ Flowmaster40 mufflers
833 23 spline 4 speed w/Hurst V Gate shifter and Centerforce DF clutch
8-3/4" 742 rear end. Richmond 4.10 gears with Auburn sure-grip. custom drive shaft with large yoke/joint
SS springs with snubber
28 x 9 Hoosier slicks

I've never run it with slicks prior, always street tires but I do have a scattershield and drive shaft loop. Obviously could never get it too hook even before the performance upgrades with street tires and stock clutch, usually 2.2-2.35 60 ft times and best 1/4 was 13.9@102. Hoping now for 1.8 or better 60 ft, along with low 13's or high 12's for 1/4. Comp Cam's online dyno page is giving my setup around 435hp depending on how you classify my headers/intake/heads, not sure what to think of that.

What do you guys think she will run?
