Help my crap 60ft times!

I think that shift point is still going to be too high. Id start at 5600 and work my way up from there in 200 RPM increments until it stops getting faster.

I don't know how my heads flow compared to yours, but I've got a junkyard shortblock 5.9 magnum, Iron Ram 1.9 valve heads, 224/230 hydraulic roller, Air Gap, 670 street avenger VS carb, 1-5/8 headers, 2.5" exhaust with super turbo mufflers (dumps), 4.11 gear, 27*9 Hoosier DOT, car weighs 3270 with me. I've got a 3800 converter. Last weekend I ran 11.79 @ 111 and had to let off 75 feet before the traps because my motor only turns about 6300 rpm. This was on a 1.63 60', which is so-so for the car so far.

My car will "pull" to 6300 or so, but runs quickest when I shift at 5600 RPMs.

Based on my anecdotal evidence, I think your car would be much quicker than 106 mph. I think mine would do 114 or better with a 3.91 gear, and probably would pick up with a double pumper carb (again with less gear).

There's 60' time in carb tuning (squirters and cams), especially on a footbrake car, so I'd check that out in addition to the suspension stuff.

Good luck!
