I'd say that certainly acceptable for the first time out.
No roll bar, so I don't know how much quicker you can go before they start telling you to slow it down.
As someone who ran well into the 10's with the OE 5/16" line and a mechanical pump, my advice is.... Put a bigger line on it. With the 383 in my car, I went from the OE 5/16" line/mechanical pump to a cell with a Mallory 140 pump and 1/2" line..... Added a fresh air hood(not sealed to the carb), and took out 100lbs........ And went from 119mph to 123mph. All I could think of was, "I wish I had done it when I had the 448 in the car".
68 Satellite, 383 with stock 906’s, 3550lbs, 11.18@123 Dealer for Comp Cams/Indy Heads

that's not terrible. And you have room to grow. I wouldn't go down on the Pro's (you are talking about the radials right?) When you go WOT at idle it's like dropping the clutch at 3+K. You might sing less if you load up the converter some. I always like to come off just above idle (1200 or so) I tried everything to get my old 70 to hook, new slicks, new shocks (front and rear) and nothing seemed to work, the "butt end" lifted to much, I went with Cal-Tracks, never got to the track with them, but they seemed to work well on the street.

Love that car! Husband's Challenger runs 11.7's @ 113, with 1.61 sixty foot on M/T ET street drag radials. What tires do you have? Better hook will definitely get that ET down. M/T ET Street Pro's in 275/60/15

Play with that tire pressure, our Challenger actually hooks best at 18-19 PSI. I was at 21 psi. The car left straight and true save for the time I spun hard off the line. Very happy with that aspect..

Going to Indy swap meet and posts like this are what make me go work on my car to get it going. 470" stroker with mch done up stealth heads should be a bit quicker than my old ~8.8:1 383 I had in it that ran 14.5's. So thanks for posting! Now off to set the motor in. Then gotta switch the 8 3/4 to the strange 60 and get a driveshaft made. Pretty excited! Haha, I have a Dana 60 waiting in the wings. May wait until Fall to see if I need to mini tub the car for traction. I'll be at Mo-Kan April 9th for the Mopar event and then again for the HAMB drags. Come by and say Hi. You can fit a 10 x 29 I bet, should be plenty

after looking at the car you need to get the butt end down. You should also make sure you have enough front end travel. The tire size is not the problem, guys run 9's on 275 drag radials. The era of "big tire" cars is over. I'm guessing with that mph you should be in the 1.50ish 60 foot range. That's what I was shooting for. That's exactly where I want to be with 60 ft. I've flipped the front spring hangers before to lower it and may try that, but I'll have to check pinion angle.

I've flipped the front spring hangers before to lower it and may try that, but I'll have to check pinion angle. With my old 440 and a best et of 11.49 @ 116 it had a best 60 ft of 1.57 but would average around a 1.60 and sometimes hitting high 1.50's on good tracks. That was on just SS springs. I agree that when you get the hook working good you should be running 11.30's to 11.40's with the 117 mph and 60 ft's in the low 1.60's to high 1.50's. If you go to Cal Tracs and really hook it may even 60 ft better. But thats if you get real serious about going after that 60 ft. My car now 60's in the low 1.50's with a 1.50 best 60 and its just average for a 10.70 car on SS springs. Good luck with your car. Ron PS: D-50 thats a very nice Demon.

Try just a pound or two less on the tires and get yourself a set Calvert 90/10s up front. Will do! I was eyeing the Calverts but got a smokin' deal on these CE 3 ways.
