1) Adjustable shocks up front, like HALs, set on 1 to 3

5) 3 way rear drag shocks set to middle position
6) Hotchkiss or similar lower control arms
7) VERY IMPORTANT: Metco instant center brackets
8) air bag on passenger rear set on 15-20psi
9) good sized rear gear, 3.73 and up
10) cam sized to provide maximum torque at stall speed of converter, or size converter to flash to cam's maximum torque RPM
11) STICKY tires
12) Line-Loc control for good burnouts
13) Keep tires spinning all the way to the lights
14) NAIL the throttle HARD from just above idle and let the converter flash
On my stock bottom 350 Impala, I got a 1.87 NA and a 1.67 on the juice, which is really not all that good, but with a bit more practice and tweaking, I probably could have cut another 1/2 tenth out of it.
I did run a TH400 tranny, which really hurt at the take-off due to the fairly tall 1st gear of 2.48. With a 4L60E, my guess is I could probably have cut a 1.77-1.79 NA and a 1.57-1.59 on the juice.
On the juice, I hooked so hard that the rims flattened the tires down to the ground and my neck snapped hard against the headrest, but as the suspension unloaded, I started spinning around 30' out. As I said, I needed more tweaking and practice.
