I'm trying to figure out how to drop my 60'. Best I can muster is 2.00

Here's my video:
015 GTO vs Monte Carlo:

Here's what I have:
LS6/4L80 (Rev Maxx 3400 stall) - both stock
Front suspension - Speedway circle track uppers, QA1 coil over shock "R" 300# (valving left in the middle)
Rear suspension - Ford 9" with 4.11 gears, solid lower control arms with poly bushings, adjustable uppers, trick springs, comp engineering shocks set to 50/50.
Tires - Nittos 555 275/50/15
Dynod @ 357 HP and 345 Tq
Max brake stand is 2k RPM before I push through the brakes

What rpm are u leaving at?

 

[Slow85SS]

2k RPM

I'd try leaving at 1200-1500.

X2, that's why I asked what rpm ur leaving at. If ur leaving at the brink of pushing thru the brakes then ur not allowing the converter to flash, which in turn "shocks" the suspension and makes the car leave harder usually resulting in better 60's

Im also very surprised that on a 3400 stall your only able to stall up to 2000 before it starts pushing through the brakes. Sounds like the converter is way tight. Whats it flash to just smashing on it?

 

[Slow85SS]

It flashes to 2500.

yeah, converter is way tight. You put a true (good) 3400-3800 converter behind that motor and it will be a world of difference.
