Looking for suggestions for my Street and Some Strip 72

[PebbleHill]

Hi guys, I've been doing some upgrades on my old 72 SWB and I'm at a crossroads. To spray or not to spray. Truck started out as a weekend toy and ended up at the drag strip and I love it ! Built the stock 350 .30 over, SRP Forged flat tops, Vortec heads with screw in studs and guide plates, 500 lift solid flat tappet cam,254/254 at.50 and 110/118 llobe Sep ,MSD pro billet distributor,6AL box with 6200 pill,Stock crank polished and balanced, forged Scat I beam rods, RPM Air Gap intake, AED 750 HP/HO carb, TH350 with shift kit, 2600 Stall, Detroit True Trac rear end with 373 gear and 275/60/15 on 8 in rally it went 8.30 at 80 mph. 60ft sucked at 2.1 on street tires..Looking at getting some new MT ET Street SS in 275/60/15 or ET Street R in 255/60/15 to give me a little more gear..What would you next besides drag radials to get me in the high 7"s and still be stretchable ?
Tapped the rings for a 150 shot but want to get in the 7"s without NOS.
Thanks
Mark
