Car just seems to not want to 60 very hard. This isn't a 1.8 car. Rear end doesn't look like it's separating to me. Any suggestions?
Is the car spinning at all? It's hard to tell from the video, but it looks like it's hooking up and going. Also, what is the weight? The MPH seems way down for making 500rwhp unless she is very heavy. My old cam/converter Camaro was ~3100lbs, but with stock suspension she ran the same et of 11.69 but at 115mph with a 1.55 60ft. running a cheap TCI 3500 converter and 275/60 MT's and 3.23 gears and dynoed 360rwhp on a Dynojet. My guess is yours should be running at least 10.80's @ 124 since you're in AZ and not some crazy high elevation. I don't see a huge mismatch in your mods, so something just doesn't seem to add up.
Sorry not super helpful, but just trying to give some input based on what I watched
Get the tires hot first and foremost.. Are you on a trans brake and what RPM are you launching at? Suspension set up right? Tires make a difference and nice hit BTW..

I’m curious what cam you’re running. You should be 11.0 or better with those hp/tq numbers. I would move up to a 4K stall, but that’s not necessarily your problem. I run a 4K stall, 3.90 gears and a 26x10.5 MT et street R bias ply and was pulling 1.6 60’....stock front struts, no sway bar and rear Viking shocks but not sure of the setting as mu buddy set them up. I also cross the line at 66-6700. More gear is going to help some, but a taller tire will lower rpm at the line

car is hooking up once I added 3 clicks to the rebound, but now it's lazier off the line, the first pass it hit the tires extremely hard and the car pulled hard left. Full weight car plus driver and 9 inch. AZ may not be high in elevation but the air is still bad. Average DA is 3500 at that track. Over 5000 in tuscon.

no brake. Tried flash and foot brake. The car went better when it was flashed. Suspension is in question, it's definitely not optimized but I'm not sure where to go from here. I'm thinking the front needs to come up faster.

If its already dead hooking you don't need the front end coming up quicker.
I may have missed it. what size tire are you running ?

You don't need more gear to take 2 to 3 tenths off that sixty. What's the tune like during launch? Are you logging?
not really, car was tuned by nicd and I have full faith and confidence the engine is running correctly. I was using torque app to monitor and log various parameters. Nothing was knocking, no issues with fuel or voltage. Everything seems fine.
You’re correct but he needs more gear to be at a higher trap rpm
His trap will gain simply from getting a better 60'. Something is holding it back out of the hole.

You really need to get either HPT or EFI and log the pass. You dont know if somethings happening during launch, or what your converter slip is on the top end which could also be the problem. My guess is either its not on all 8 cylinders, your converter is lousy, or something is off in the tune. I would also take a look at MAP on the big end and see if you have an intake restriction. I went 1.6x on an intake/exhaust stock LS1 with a 3200 stall.

11.60 402 and it won't 60
