Maybe try Nitto drag radials if they still make 18’s.
Looking for stick 18inch tires

I don't see a 383 with nitrous making 1000 ft/lbs. Have a dyno graph? That's the most impressive 383 on nitrous number I've ever seen. How big of a shot? I haven't seen a 383 LS make much over 500 rwhp NA. I went 6.58 and 10.2x on a 150 shot with a 408 15 years ago, but I was only 632 rwhp and less torque than that. I don't doubt your times at all just the 1000 ft/lbs dyno number. I hope to get to the 1/4 mile track next year, should go very low in the 9's.
Current combo is a 377 with 20 psi peak boost so torque isn't even it's game. Never been on a dyno, but trap speed suggests at least 800 rwhp. Torque might only be 600 though if I were to guess. I'm making more power now then I did the last time I was at the track. Nothing open here now obviously with below freezing temps and a blizzard on the way...lol. Not sure what changes I'll make for next year. Thinking at least a bigger blower f1a-94 most likely, but haven't ruled out an f1x and 4l80e conversion yet if I feel like spending that kind of money.
I found my old dyno from the 408 w/150 shot from around 2006. Unfortunately now I remember we couldn't get a tach signal or torque reading. We didn't want to keep making pulls with nitrous so all I have is a hp at mph graph. The two lines are both hp for two different pulls. No torque reading.
