Default Looking for 60' help...suggestions?

I'm wanting to get my 60's back to where they were last year before all my changes. I made a lot of changes to help my car run more mph and lost some 60'. Last year, my typical 60' was around 1.52. This year I'm at 1.60ish.

I went from a too loose converter that flashed to 4700 (but slipped big time at the stripe) to a Continental 10" that flashes to 4000 but is a lot tighter down track. Torker II intake to a Northwind. Q850 carb to a Q950. SFT 255/266 106 LSA 103 ICL cam to a street roller 254/260 112LSA 108 ICL. I've only ran it in the 1/8 mile and 60's are about .08 worse, ET is really about the same, and mph is up about 2 mph. I know the extra mph will really help my 1/4 ET, but really want to get my 60's back down too.

The car dead hooks and it doesn't lift the front or separate the rear excessively. Carb is pretty much dialed in. A/F graph looks pretty good, maybe a little rich in low gear. Launching on the footbrake from about 1800. Not sure where to turn next. Will suspension tuning help on a car that doesn't spin or have any excessive lift? Thanks in advance for any suggestions!
